The Elasticsearch docs are in AsciiDoc format and can be built using the Elasticsearch documentation build process.
Snippets marked with // CONSOLE
are automatically annotated with "VIEW IN
SENSE" in the documentation and are automatically tested by the command
gradle :docs:check
. By default // CONSOLE
snippet runs as its own isolated
test. You can manipulate the test execution in the following ways:
-
// TEST
: Explicitly marks a snippet as a test. Snippets marked this way are tests even if they don’t have// CONSOLE
. -
// TEST[s/foo/bar/]
: Replacefoo
withbar
in the test. This should be used sparingly because it makes the test "lie". Sometimes, though, you can use it to make the tests more clear. -
// TEST[catch:foo]
: Used to expect errors in the requests. Replacefoo
withrequest
to expect a 400 error, for example. If the snippet contains multiple requests then only the last request will expect the error. -
// TEST[continued]
: Continue the test started in the last snippet. Between tests the nodes are cleaned: indexes are removed, etc. This will prevent that. This is really useful when you have text and snippets that work together to tell the story of some use case because it merges the snippets (and thus the use case) into one big test. -
// TEST[skip:reason]
: Skip this test. Replacereason
with the actual reason to skip the test. Snippets without// TEST
or// CONSOLE
aren’t considered tests anyway but this is useful for explicitly documenting the reason why the test shouldn’t be run. -
// TEST[setup:name]
: Run some setup code before running the snippet. This is useful for creating and populating indexes used in the snippet. The setup code is defined indocs/build.gradle
. -
// TEST[warning:some warning]
: Expect the response to include aWarning
header. If the response doesn’t include aWarning
header with the exact text then the test fails. If the response includesWarning
headers that aren’t expected then the test fails. -
// TESTRESPONSE
: Matches this snippet against the body of the response of the last test. If the response is JSON then order is ignored. With// TEST[continued]
you can make tests that contain multiple command snippets and multiple response snippets. -
// TESTRESPONSE[s/foo/bar/]
: Substitutions. See// TEST[s/foo/bar]
. -
// TESTRESPONSE[_cat]
: Add substitutions for testing_cat
responses. Use this after all other substitutions so it doesn’t make other substitutions difficult. -
// TESTSETUP
: Marks this snippet as the "setup" for all other snippets in this file. This is a somewhat natural way of structuring documentation. You say "this is the data we use to explain this feature" then you add the snippet that you mark// TESTSETUP
and then every snippet will turn into a test that runs the setup snippet first. See the "painless" docs for a file that puts this to good use. This is fairly similar to// TEST[setup:name]
but rather than the setup defined indocs/build.gradle
the setup is defined right in the documentation file.
Any place you can use json you can use elements like $body.path.to.thing
which is replaced on the fly with the contents of the thing at path.to.thing
in the last response.
