6.9 Stub Runner Docker

We’re publishing a spring-cloud/spring-cloud-contract-stub-runner Docker image +that will start the standalone version of Stub Runner.

If you want to learn more about the basics of Maven, artifact ids, +group ids, classifiers and Artifact Managers, just click here Section 4.5, “Docker Project”.

6.9.1 How to use it

Just execute the docker image. You can pass any of the Section 6.8.1, “Common Properties for JUnit and Spring” +as environment variables. The convention is that all the +letters should be upper case. The camel case notation should +and the dot (.) should be separated via underscore (_). E.g. + the stubrunner.repositoryRoot property should be represented + as a STUBRUNNER_REPOSITORY_ROOT environment variable.

6.9.2 Example of client side usage in a non JVM project

We’d like to use the stubs created in this Section 4.5.4, “Server side (nodejs)” step. +Let’s assume that we want to run the stubs on port 9876. The NodeJS code +is available here:

$ git clone https://github.com/spring-cloud-samples/spring-cloud-contract-nodejs
+$ cd bookstore

Let’s run the Stub Runner Boot application with the stubs.

# Provide the Spring Cloud Contract Docker version
+$ SC_CONTRACT_DOCKER_VERSION="..."
+# The IP at which the app is running and Docker container can reach it
+$ APP_IP="192.168.0.100"
+# Spring Cloud Contract Stub Runner properties
+$ STUBRUNNER_PORT="8083"
+# Stub coordinates 'groupId:artifactId:version:classifier:port'
+$ STUBRUNNER_IDS="com.example:bookstore:0.0.1.RELEASE:stubs:9876"
+$ STUBRUNNER_REPOSITORY_ROOT="http://${APP_IP}:8081/artifactory/libs-release-local"
+# Run the docker with Stub Runner Boot
+$ docker run  --rm -e "STUBRUNNER_IDS=${STUBRUNNER_IDS}" -e "STUBRUNNER_REPOSITORY_ROOT=${STUBRUNNER_REPOSITORY_ROOT}" -p "${STUBRUNNER_PORT}:${STUBRUNNER_PORT}" -p "9876:9876" springcloud/spring-cloud-contract-stub-runner:"${SC_CONTRACT_DOCKER_VERSION}"

What’s happening is that

  • a standalone Stub Runner application got started
  • it downloaded the stub with coordinates com.example:bookstore:0.0.1.RELEASE:stubs on port 9876
  • it got downloaded from Artifactory running at http://192.168.0.100:8081/artifactory/libs-release-local
  • after a while Stub Runner will be running on port 8083
  • and the stubs will be running at port 9876

On the server side we built a stateful stub. Let’s use curl to assert +that the stubs are setup properly.

# let's execute the first request (no response is returned)
+$ curl -H "Content-Type:application/json" -X POST --data '{ "title" : "Title", "genre" : "Genre", "description" : "Description", "author" : "Author", "publisher" : "Publisher", "pages" : 100, "image_url" : "https://d213dhlpdb53mu.cloudfront.net/assets/pivotal-square-logo-41418bd391196c3022f3cd9f3959b3f6d7764c47873d858583384e759c7db435.svg", "buy_url" : "https://pivotal.io" }' http://localhost:9876/api/books

Spring Cloud Contract Verifier also generates tests with a guaranteed order of execution.

4.5 Docker Project

We’re publishing a springcloud/spring-cloud-contract Docker image +that contains a project that will generate tests and execute them in EXPLICIT mode +against a running application.

[Tip]Tip

The EXPLICIT mode means that the tests generated from contracts will send +real requests and not the mocked ones.

4.5.1 Short intro to Maven, JARs and Binary storage

Since the Docker image can be used by non JVM projects, it’s good to +explain the basic terms behind Spring Cloud Contract packaging defaults.

Part of the following definitions were taken from the Maven Glossary

  • Project: Maven thinks in terms of projects. Everything that you +will build are projects. Those projects follow a well defined +“Project Object Model”. Projects can depend on other projects, +in which case the latter are called “dependencies”. A project may +consistent of several subprojects, however these subprojects are still +treated equally as projects.
  • Artifact: An artifact is something that is either produced or used +by a project. Examples of artifacts produced by Maven for a project +include: JARs, source and binary distributions. Each artifact +is uniquely identified by a group id and an artifact ID which is +unique within a group.
  • JAR: JAR stands for Java ARchive. It’s a format based on +the ZIP file format. Spring Cloud Contract packages the contracts and generated +stubs in a JAR file.
  • GroupId: A group ID is a universally unique identifier for a project. +While this is often just the project name (eg. commons-collections), +it is helpful to use a fully-qualified package name to distinguish it +from other projects with a similar name (eg. org.apache.maven). +Typically, when published to the Artifact Manager, the GroupId will get +slash separated and form part of the URL. E.g. for group id com.example +and artifact id application would be /com/example/application/.
  • Classifier: The Maven dependency notation looks as follows: +groupId:artifactId:version:classifier. The classifier is additional suffix +passed to the dependency. E.g. stubs, sources. The same dependency +e.g. com.example:application can produce multiple artifacts that +differ from each other with the classifier.
  • Artifact manager: When you generate binaries / sources / packages, you would +like them to be available for others to download / reference or reuse. In case +of the JVM world those artifacts would be JARs, for Ruby these are gems +and for Docker those would be Docker images. You can store those artifacts +in a manager. Examples of such managers can be Artifactory +or Nexus.

4.5.2 How it works

The image searches for contracts under the /contracts folder. +The output from running the tests will be available under +/spring-cloud-contract/build folder (it’s useful for debugging +purposes).

It’s enough for you to mount your contracts, pass the environment variables + and the image will:

  • generate the contract tests
  • execute the tests against the provided URL
  • generate the WireMock stubs
  • (optional - turned on by default) publish the stubs to a Artifact Manager

Environment Variables

The Docker image requires some environment variables to point to +your running application, to the Artifact manager instance etc.

  • PROJECT_GROUP - your project’s group id. Defaults to com.example.
  • PROJECT_VERSION - your project’s version. Defaults to 0.0.1-SNAPSHOT
  • PROJECT_NAME - artifact id. Defaults to example
  • REPO_WITH_BINARIES_URL - URL of your Artifact Manager. Defaults to http://localhost:8081/artifactory/libs-release-local +which is the default URL of Artifactory running locally
  • REPO_WITH_BINARIES_USERNAME - (optional) username when the Artifact Manager is secured
  • REPO_WITH_BINARIES_PASSWORD - (optional) password when the Artifact Manager is secured
  • PUBLISH_ARTIFACTS - if set to true then will publish artifact to binary storage. Defaults to true.

These environment variables are used when tests are executed:

  • APPLICATION_BASE_URL - url against which tests should be executed. +Remember that it has to be accessible from the Docker container (e.g. localhost +will not work)
  • APPLICATION_USERNAME - (optional) username for basic authentication to your application
  • APPLICATION_PASSWORD - (optional) password for basic authentication to your application

4.5.3 Example of usage

Let’s take a look at a simple MVC application

$ git clone https://github.com/spring-cloud-samples/spring-cloud-contract-nodejs
+$ cd bookstore

The contracts are available under /contracts folder.

4.5.4 Server side (nodejs)

Since we want to run tests, we could just execute:

$ npm test

however, for learning purposes, let’s split it into pieces:

# Stop docker infra (nodejs, artifactory)
+$ ./stop_infra.sh
+# Start docker infra (nodejs, artifactory)
+$ ./setup_infra.sh
+
+# Kill & Run app
+$ pkill -f "node app"
+$ nohup node app &
+
+# Prepare environment variables
+$ SC_CONTRACT_DOCKER_VERSION="..."
+$ APP_IP="192.168.0.100"
+$ APP_PORT="3000"
+$ ARTIFACTORY_PORT="8081"
+$ APPLICATION_BASE_URL="http://${APP_IP}:${APP_PORT}"
+$ ARTIFACTORY_URL="http://${APP_IP}:${ARTIFACTORY_PORT}/artifactory/libs-release-local"
+$ CURRENT_DIR="$( pwd )"
+$ CURRENT_FOLDER_NAME=${PWD##*/}
+$ PROJECT_VERSION="0.0.1.RELEASE"
+
+# Execute contract tests
+$ docker run  --rm -e "APPLICATION_BASE_URL=${APPLICATION_BASE_URL}" -e "PUBLISH_ARTIFACTS=true" -e "PROJECT_NAME=${CURRENT_FOLDER_NAME}" -e "REPO_WITH_BINARIES_URL=${ARTIFACTORY_URL}" -e "PROJECT_VERSION=${PROJECT_VERSION}" -v "${CURRENT_DIR}/contracts/:/contracts:ro" -v "${CURRENT_DIR}/node_modules/spring-cloud-contract/output:/spring-cloud-contract-output/" springcloud/spring-cloud-contract:"${SC_CONTRACT_DOCKER_VERSION}"
+
+# Kill app
+$ pkill -f "node app"

What will happen is that via bash scripts:

  • infrastructure will be set up (MongoDb, Artifactory). +In real life scenario you would just run the NodeJS application +with mocked database. In this example we want to show how we can +benefit from Spring Cloud Contract in no time.

  • due to those constraints the contracts also represent the +stateful situation

    • first request is a POST that causes data to get inserted to the database
    • second request is a GET that returns a list of data with 1 previously inserted element
  • the NodeJS application will be started (on port 3000)

  • contract tests will be generated via Docker and tests +will be executed against the running application

    • the contracts will be taken from /contracts folder.
    • the output of the test execution is available under +node_modules/spring-cloud-contract/output.
  • the stubs will be uploaded to Artifactory. You can check them out +under http://localhost:8081/artifactory/libs-release-local/com/example/bookstore/0.0.1.RELEASE/ . +The stubs will be here http://localhost:8081/artifactory/libs-release-local/com/example/bookstore/0.0.1.RELEASE/bookstore-0.0.1.RELEASE-stubs.jar.

Spring Cloud Contract Verifier also generates tests with a guaranteed order of execution.

4.5 Docker Project

We’re publishing a springcloud/spring-cloud-contract Docker image +that contains a project that will generate tests and execute them in EXPLICIT mode +against a running application.

[Tip]Tip

The EXPLICIT mode means that the tests generated from contracts will send +real requests and not the mocked ones.

4.5.1 Short intro to Maven, JARs and Binary storage

Since the Docker image can be used by non JVM projects, it’s good to +explain the basic terms behind Spring Cloud Contract packaging defaults.

Part of the following definitions were taken from the Maven Glossary

  • Project: Maven thinks in terms of projects. Everything that you +will build are projects. Those projects follow a well defined +“Project Object Model”. Projects can depend on other projects, +in which case the latter are called “dependencies”. A project may +consistent of several subprojects, however these subprojects are still +treated equally as projects.
  • Artifact: An artifact is something that is either produced or used +by a project. Examples of artifacts produced by Maven for a project +include: JARs, source and binary distributions. Each artifact +is uniquely identified by a group id and an artifact ID which is +unique within a group.
  • JAR: JAR stands for Java ARchive. It’s a format based on +the ZIP file format. Spring Cloud Contract packages the contracts and generated +stubs in a JAR file.
  • GroupId: A group ID is a universally unique identifier for a project. +While this is often just the project name (eg. commons-collections), +it is helpful to use a fully-qualified package name to distinguish it +from other projects with a similar name (eg. org.apache.maven). +Typically, when published to the Artifact Manager, the GroupId will get +slash separated and form part of the URL. E.g. for group id com.example +and artifact id application would be /com/example/application/.
  • Classifier: The Maven dependency notation looks as follows: +groupId:artifactId:version:classifier. The classifier is additional suffix +passed to the dependency. E.g. stubs, sources. The same dependency +e.g. com.example:application can produce multiple artifacts that +differ from each other with the classifier.
  • Artifact manager: When you generate binaries / sources / packages, you would +like them to be available for others to download / reference or reuse. In case +of the JVM world those artifacts would be JARs, for Ruby these are gems +and for Docker those would be Docker images. You can store those artifacts +in a manager. Examples of such managers can be Artifactory +or Nexus.

4.5.2 How it works

The image searches for contracts under the /contracts folder. +The output from running the tests will be available under +/spring-cloud-contract/build folder (it’s useful for debugging +purposes).

It’s enough for you to mount your contracts, pass the environment variables + and the image will:

  • generate the contract tests
  • execute the tests against the provided URL
  • generate the WireMock stubs
  • (optional - turned on by default) publish the stubs to a Artifact Manager

Environment Variables

The Docker image requires some environment variables to point to +your running application, to the Artifact manager instance etc.

  • PROJECT_GROUP - your project’s group id. Defaults to com.example.
  • PROJECT_VERSION - your project’s version. Defaults to 0.0.1-SNAPSHOT
  • PROJECT_NAME - artifact id. Defaults to example
  • REPO_WITH_BINARIES_URL - URL of your Artifact Manager. Defaults to http://localhost:8081/artifactory/libs-release-local +which is the default URL of Artifactory running locally
  • REPO_WITH_BINARIES_USERNAME - (optional) username when the Artifact Manager is secured
  • REPO_WITH_BINARIES_PASSWORD - (optional) password when the Artifact Manager is secured
  • PUBLISH_ARTIFACTS - if set to true then will publish artifact to binary storage. Defaults to true.

These environment variables are used when tests are executed:

  • APPLICATION_BASE_URL - url against which tests should be executed. +Remember that it has to be accessible from the Docker container (e.g. localhost +will not work)
  • APPLICATION_USERNAME - (optional) username for basic authentication to your application
  • APPLICATION_PASSWORD - (optional) password for basic authentication to your application

4.5.3 Example of usage

Let’s take a look at a simple MVC application

$ git clone https://github.com/spring-cloud-samples/spring-cloud-contract-nodejs
+$ cd bookstore

The contracts are available under /contracts folder.

4.5.4 Server side (nodejs)

Since we want to run tests, we could just execute:

$ npm test

however, for learning purposes, let’s split it into pieces:

# Stop docker infra (nodejs, artifactory)
+$ ./stop_infra.sh
+# Start docker infra (nodejs, artifactory)
+$ ./setup_infra.sh
+
+# Kill & Run app
+$ pkill -f "node app"
+$ nohup node app &
+
+# Prepare environment variables
+$ SC_CONTRACT_DOCKER_VERSION="..."
+$ APP_IP="192.168.0.100"
+$ APP_PORT="3000"
+$ ARTIFACTORY_PORT="8081"
+$ APPLICATION_BASE_URL="http://${APP_IP}:${APP_PORT}"
+$ ARTIFACTORY_URL="http://${APP_IP}:${ARTIFACTORY_PORT}/artifactory/libs-release-local"
+$ CURRENT_DIR="$( pwd )"
+$ CURRENT_FOLDER_NAME=${PWD##*/}
+$ PROJECT_VERSION="0.0.1.RELEASE"
+
+# Execute contract tests
+$ docker run  --rm -e "APPLICATION_BASE_URL=${APPLICATION_BASE_URL}" -e "PUBLISH_ARTIFACTS=true" -e "PROJECT_NAME=${CURRENT_FOLDER_NAME}" -e "REPO_WITH_BINARIES_URL=${ARTIFACTORY_URL}" -e "PROJECT_VERSION=${PROJECT_VERSION}" -v "${CURRENT_DIR}/contracts/:/contracts:ro" -v "${CURRENT_DIR}/node_modules/spring-cloud-contract/output:/spring-cloud-contract-output/" springcloud/spring-cloud-contract:"${SC_CONTRACT_DOCKER_VERSION}"
+
+# Kill app
+$ pkill -f "node app"

What will happen is that via bash scripts:

  • infrastructure will be set up (MongoDb, Artifactory). +In real life scenario you would just run the NodeJS application +with mocked database. In this example we want to show how we can +benefit from Spring Cloud Contract in no time.

  • due to those constraints the contracts also represent the +stateful situation

    • first request is a POST that causes data to get inserted to the database
    • second request is a GET that returns a list of data with 1 previously inserted element
  • the NodeJS application will be started (on port 3000)

  • contract tests will be generated via Docker and tests +will be executed against the running application

    • the contracts will be taken from /contracts folder.
    • the output of the test execution is available under +node_modules/spring-cloud-contract/output.
  • the stubs will be uploaded to Artifactory. You can check them out +under http://localhost:8081/artifactory/libs-release-local/com/example/bookstore/0.0.1.RELEASE/ . +The stubs will be here http://localhost:8081/artifactory/libs-release-local/com/example/bookstore/0.0.1.RELEASE/bookstore-0.0.1.RELEASE-stubs.jar.

To see how the client side looks like check out the Section 6.9, “Stub Runner Docker” section.

5. Spring Cloud Contract Verifier Messaging

Spring Cloud Contract Verifier lets you verify applications that uses messaging as a means of communication. All of the integrations shown in this document work with Spring, but you can also create one of your own and use that.

5.1 Integrations

You can use one of the following four integration configurations:

  • Apache Camel
  • Spring Integration
  • Spring Cloud Stream
  • Spring AMQP

Since we use Spring Boot, if you have added one of these libraries to the classpath, all the messaging configuration is automatically set up.

port means the port of the WireMock server.

[Important]Important

Starting with version 1.0.4, you can provide a range of versions that you would like the Stub Runner to take into consideration. You can read more about the Aether versioning -ranges here.

7. Stub Runner for Messaging

Stub Runner can run the published stubs in memory. It can integrate with the following +ranges here.

6.9 Stub Runner Docker

We’re publishing a spring-cloud/spring-cloud-contract-stub-runner Docker image +that will start the standalone version of Stub Runner.

If you want to learn more about the basics of Maven, artifact ids, +group ids, classifiers and Artifact Managers, just click here Section 4.5, “Docker Project”.

6.9.1 How to use it

Just execute the docker image. You can pass any of the Section 6.8.1, “Common Properties for JUnit and Spring” +as environment variables. The convention is that all the +letters should be upper case. The camel case notation should +and the dot (.) should be separated via underscore (_). E.g. + the stubrunner.repositoryRoot property should be represented + as a STUBRUNNER_REPOSITORY_ROOT environment variable.

6.9.2 Example of client side usage in a non JVM project

We’d like to use the stubs created in this Section 4.5.4, “Server side (nodejs)” step. +Let’s assume that we want to run the stubs on port 9876. The NodeJS code +is available here:

$ git clone https://github.com/spring-cloud-samples/spring-cloud-contract-nodejs
+$ cd bookstore

Let’s run the Stub Runner Boot application with the stubs.

# Provide the Spring Cloud Contract Docker version
+$ SC_CONTRACT_DOCKER_VERSION="..."
+# The IP at which the app is running and Docker container can reach it
+$ APP_IP="192.168.0.100"
+# Spring Cloud Contract Stub Runner properties
+$ STUBRUNNER_PORT="8083"
+# Stub coordinates 'groupId:artifactId:version:classifier:port'
+$ STUBRUNNER_IDS="com.example:bookstore:0.0.1.RELEASE:stubs:9876"
+$ STUBRUNNER_REPOSITORY_ROOT="http://${APP_IP}:8081/artifactory/libs-release-local"
+# Run the docker with Stub Runner Boot
+$ docker run  --rm -e "STUBRUNNER_IDS=${STUBRUNNER_IDS}" -e "STUBRUNNER_REPOSITORY_ROOT=${STUBRUNNER_REPOSITORY_ROOT}" -p "${STUBRUNNER_PORT}:${STUBRUNNER_PORT}" -p "9876:9876" springcloud/spring-cloud-contract-stub-runner:"${SC_CONTRACT_DOCKER_VERSION}"

What’s happening is that

  • a standalone Stub Runner application got started
  • it downloaded the stub with coordinates com.example:bookstore:0.0.1.RELEASE:stubs on port 9876
  • it got downloaded from Artifactory running at http://192.168.0.100:8081/artifactory/libs-release-local
  • after a while Stub Runner will be running on port 8083
  • and the stubs will be running at port 9876

On the server side we built a stateful stub. Let’s use curl to assert +that the stubs are setup properly.

# let's execute the first request (no response is returned)
+$ curl -H "Content-Type:application/json" -X POST --data '{ "title" : "Title", "genre" : "Genre", "description" : "Description", "author" : "Author", "publisher" : "Publisher", "pages" : 100, "image_url" : "https://d213dhlpdb53mu.cloudfront.net/assets/pivotal-square-logo-41418bd391196c3022f3cd9f3959b3f6d7764c47873d858583384e759c7db435.svg", "buy_url" : "https://pivotal.io" }' http://localhost:9876/api/books
+# Now time for the second request
+$ curl -X GET http://localhost:9876/api/books
+# You will receive contents of the JSON

7. Stub Runner for Messaging

Stub Runner can run the published stubs in memory. It can integrate with the following frameworks:

  • Spring Integration
  • Spring Cloud Stream
  • Apache Camel
  • Spring AMQP

It also provides entry points to integrate with any other solution on the market.

[Important]Important

If you have multiple frameworks on the classpath Stub Runner will need to define which one should be used. Let’s assume that you have both AMQP, Spring Cloud Stream and Spring Integration on the classpath. Then you need to set stubrunner.stream.enabled=false and stubrunner.integration.enabled=false. diff --git a/1.2.x/spring-cloud-contract-maven-plugin/checkstyle.html b/1.2.x/spring-cloud-contract-maven-plugin/checkstyle.html index c0b14ffacd..5354d09d0b 100644 --- a/1.2.x/spring-cloud-contract-maven-plugin/checkstyle.html +++ b/1.2.x/spring-cloud-contract-maven-plugin/checkstyle.html @@ -1,13 +1,13 @@ - + Spring Cloud Contract Maven Plugin – Checkstyle Results @@ -146,7 +146,7 @@
