test_suite()

A test_suite() is used to create a grouping of tests that should all be run by just testing this rule.

This rule can then be given to buck test, and all tests that it depends on will be invoked. Note that the test_suite() target is not tested itself, it just tells buck to run other tests. It will not show up in calls to the external runner nor in the normal test output.

Arguments

• name (required) #

  The short name for this build target.

• tests (defaults to []) #

  A list of build targets that should be tested.

• visibility (defaults to []) #

  List of build target patterns that identify the build rules that can include this rule as a dependency, for example, by listing it in their deps or exported_deps attributes. For more information, see visibility.

• licenses (defaults to []) #

  Set of license files for this library. To get the list of license files for a given build rule and all of its dependencies, you can use buck query.

• labels (defaults to []) #

  Set of arbitrary strings which allow you to annotate a build rule with tags that can be searched for over an entire dependency tree using buck query attrfilter().

Examples

This test_suite() sets up two different sets of tests to run, 'all' tests and 'slow' tests. Note that all_tests can depend on slow_tests, and all three tests are run.

# instrumentation_tests/BUCK:
sh_test(
    name = "instrumentation_tests",
    test = "instrumentation_tests.sh",
    visibility = ["PUBLIC"],
)

# integration_tests/BUCK:
sh_test(
    name = "integration_tests",
    test = "integration_tests.sh",
    visibility = ["PUBLIC"],
)

# unit_tests/BUCK:
sh_test(
    name = "unit_tests",
    test = "unit_tests.sh",
    visibility = ["PUBLIC"],
)

# BUCK:
test_suite(
    name = "slow_tests",
    tests = [
        "//instrumentation_tests:instrumentation_tests",
        "//integration_tests:integration_tests",
    ],
)

test_suite(
    name = "all_tests",
    tests = [
        ":slow_tests",
        "//unit_tests:unit_tests",
    ],
)

Yields output like this when run:

$ buck test //:slow_tests
