|
This rule essentially verifies that all targets under `targets` would
|
|
generate no errors when analyzed with `bazel build [targets] --nobuild`.
|
|
Action success/failure for the targets and their transitive dependencies
|
|
are not verified. An analysis test simply ensures that each target in the transitive
|
|
dependencies propagate providers appropriately and register actions for their outputs
|
|
appropriately.
|
|
|
|
NOTE: If the targets fail to analyze, instead of the analysis_test failing, the analysis_test
|
|
will fail to build. Ideally, it would instead result in a test failure. This is a current
|
|
infrastructure limitation that may be fixed in the future.
|
|
|
|
Typical usage:
|
|
|
|
load("@bazel_skylib//rules:analysis_test.bzl", "analysis_test")
|
|
analysis_test(
|
|
name = "my_analysis_test",
|
|
targets = [
|
|
"//some/package:rule",
|
|
],
|
|
)
|
|
|
|
Args:
|
|
name: The name of the test rule.
|
|
targets: A list of targets to ensure build.
