Example 9 with EventBus

use of com.google.common.eventbus.EventBus in project bazel by bazelbuild.

the class PrepareDepsOfPatternsFunctionSmartNegationTest method getGraphFromPatternsEvaluation.

// Helpers:

    // The evaluation has no errors if success was expected.
    assertThat(evaluationResult.hasError()).isNotEqualTo(successExpected);
    return Preconditions.checkNotNull(evaluationResult.getWalkableGraph());
}

Example 10 with EventBus

use of com.google.common.eventbus.EventBus in project bazel by bazelbuild.

the class BuildViewTest method testCircularDependencyWithLateBoundLabel.

@Test

    assertThat(result.hasError()).isTrue();
    assertContainsEvent("in cc_library rule //cycle:foo: cycle in dependency graph:");
    // This needs to be reported as an anlysis-phase cycle; the cycle only occurs due to the stl
    // command-line option, which is part of the configuration, and which is used due to the
    // late-bound label.
