Build
Every time you run automated tests, you're testing the behavior of some software. A build represents that software. Each time you send test results to Launchable, you record them against a specific build so that Launchable knows that you ran X tests against Y software with Z results.
Therefore, before you run your tests, you create a build using launchable record build.

Build attributes

Every build has two primary attributes:
  1. 2.
    Its relationships to commits in Git repositories
Let's expand on the second part: the relationship between builds and repositories.
When you record a build, you tell the CLI which source repo(s) and commit hash(es) the software was built from. For example, in the simplest case, the software is a single binary built from code in a single Git repository.
First, let's assume you've cloned the Git repository into the current directory (.) and that the relevant HEAD commit has already been checked out (e.g. 29932f39). This is typically already available if you're building software and running tests on the same machine.
So, once you've done that, the command looks like this:
1
launchable record build --name $BUILD_NAME --source src=.
Copied!
Running this command in your CI pipeline creates a build in your Launchable workspace. That build has a name (whatever $BUILD_NAME expanded to, e.g. jenkins-myproject-123) and one repository commit relation (name: src, commit: 29932f39).

Commit collection

By default, the launchable record build command also runs the launchable record commit command.
This command collects the details of the changes in each commit in your repository (not just the HEAD commit) so that changes between builds can be compared later.
By default, launchable record build runs launchable record commit, but these operations can be separated.

More complex build/test pipelines

However, in many other cases, the software being tested might be a single binary built from several repos. Furthermore, the software being tested might be the combination of several services deployed to a single testing environment. The Recording builds from multiple repositories page outlines how to instrument your pipeline in these situations.
