This commit splits Spring REST Docs into two projects –
spring-restdocs-core and spring-restdocs-mockmvc.
spring-restdocs-core contains the vast majority of the code but does not
depend on a specific test framework other than JUnit. The use of a
Spring Test TestExecutionListener has been replaced with a JUnit test
rule. The rule is declared once per test class and configured with
the output directory to which the generated snippets should be written.
This simplifies the implementation as thread local storage is no longer
required to transfer information about the test that’s running into
Spring REST Docs. Instead, this transfer is now handled by the new test
rule. It has also simplified the configuration as it’s no longer
necessary for users to provide a system property that configures the
output directory.
spring-restdocs-mockmvc contains code that’s specific to using Spring
REST Docs with Spring MVC Test’s MockMvc. This is currently the only
testing framework that’s supported, but it paves the way for adding
support for additional frameworks. REST Assured is one that users seem
particularly interested in (see gh-80 and gh-102).
Closes gh-107
This commit updates the API to improve its extensibility and
readability.
SnippetWritingResultHandler has been replaced with a more general
purpose Snippet interface. Snippets are now provided to the main
document method using varargs rather than the various with… methods
that were previously used. As a result a custom Snippet implementation
can now be used in exactly the same way as any of the built-in
snippets:
this.mockMvc.perform(get("/"))
.andExpect(status().isOk())
.andDo(document("index-example",
links(
linkWithRel("notes").description("…"),
linkWithRel("tags").description("…")),
responseFields(
fieldWithPath("_links").description("…")),
yourCustomSnippet()));
Control of the snippets that are generated by default is now available
via RestDocumentationConfigurer:
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context)
.apply(documentationConfiguration().snippets()
.withDefaults(curlRequest(), yourCustomSnippet()))
.build();
See gh-73
Previously, snippets were written to disk using the JVM’s default
encoding. While this could be controlled by the file.encoding system
property it was not ideal as, if the proper was not always set, it could
lead to platform-dependent output being generated. Furthermore,
Asciidoctor uses UTF-8 encoding by default so there was a risk of the
snippets being generated in a different encoding to the encoding
expected by Asciidoctor.
This commit updates the configuration so that, by default, snippets are
encoded as UTF-8. The RestDocumentationConfigurer API has been enhanced
to allow this default to be configured as part of building the
MockMvc instance. This enhancement as brought with it a more fluent
configuration API that separates configuration that is related to URIs
from configuration that is related to snippets.
Closes gh-67
This commit improves the support for documenting the fields found
in request and response payloads. The improvements include:
- Using the term "payload" rather than "state" as the latter is
somewhat HAL-specific
- Code simplification, including the removal of the Path abstraction
- Automatically determining the type of a field based on the payload
that's being tested
- Updating the samples to use the new API
In addition to these improvements, support for documenting field
constraints has been removed as more thought is required. The
FieldDescriptor abstraction is used to describe both request and
response fields, however it's not clear that contraints apply to both
and they certainly don't apply in the same way. For the time being at
least, users who want to document a field's constraints can do so as
part of its description.
Closes gh-24
The MVC test framework provides an alwaysDo method which allows the
configuration of a result handler to be that will be invoked for every
call to perform. Previously, this method could not be used for
producing documentation snippets as the snippets would overwrite each
other.
This commit adds support for writing snippets to a parameterized
output directory. Two parameters are supported: method name and step.
Method name is the name of the currently executing test method. Step
is a count of the number of calls to MockMvc.perform that have been
made in that method.
Closes gh-14
This commit makes extensive changes to the structure of the code. It
introduces a number of separate packages to provide better separation
of the various areas of functionality. Alongside this change the project
has been renamed from spring-restdocs-core to spring-restdocs.
The build has been improved to provide support for building the samples
from the main build using the buildSamples task. While this change has
been made, the samples remain standalone projects so that their
configuration is not dependent on the main project’s build. Running
buildSamples will build the samples using both Maven and Gradle.
All of the main project’s classes now have javadoc and licence/copyright
headers.
