Allow BWC Testing against a specific branch (#25510)
Some times we need a fix / change to have two parts in two different branches (corresponding to two different ES releases). In order to be able to test these cases you need to run the BWC tests against a local branch rather than then using a branch from `github.com/elastic/elasticsearch`. This commit adds a system property called `tests.bwc.refspec` that allows you to do it. Note that I've chosen to go with the simplest code change for now, at the expense of some user friendliness.

=== BWC Testing against a specific branch
|
||||
|
||||
Sometimes a backward compatibility change spans two versions. A common case is a new functionality
|
||||
that needs a BWC bridge in and an unreleased versioned of a release branch (for example, 5.x).
|
||||
To test the changes, you can instruct gradle to build the BWC version from a local branch instead of
|
||||
pulling the release branch from GitHub. You do so using the `tests.bwc.refspec` system property:
|
||||
|
||||
-------------------------------------------------
|
||||
gradle check -Dtests.bwc.refspec=origin/index_req_bwc_5.x
|
||||
-------------------------------------------------
|
||||
|
||||
The branch needs to be available on the local clone that the BWC makes of the repository you run the
|
||||
tests from. Using the `origin` remote is a handy trick to make sure that a branch is available
|
||||
and is up to date in the case of multiple runs.
|
||||
|
||||
Example:
|
||||
|
||||
Say you need to make a change to `master` and have a BWC layer in `5.x`. You will need to:
|
||||
. Create a branch called `index_req_change` off `master`. This will contain your change.
|
||||
. Create a branch called `index_req_bwc_5.x` off `5.x`. This will contain your bwc layer.
|
||||
. If not running the tests locally, push both branches to your remote repository.
|
||||
. Run the tests with `gradle check -Dtests.bwc.refspec=origin/index_req_bwc_5.x`
