Examples with TestAction com.google.devtools.build.lib.actions.util.TestAction used on opensource projects

Example 11 with TestAction

use of com.google.devtools.build.lib.actions.util.TestAction in project bazel by bazelbuild.

the class TimestampBuilderTest method testMissingSourceFileIsAnError.

@Test
public void testMissingSourceFileIsAnError() throws Exception {
    // A missing input to an action must be treated as an error because there's
    // a risk that the action that consumes it will succeed, but with a
    // different behavior (imagine that it globs over the directory, for
    // example).  It's not ok to simply try the action and let the action
    // report "input file not found".
    //
    // (However, there are exceptions to this principle: C++ compilation
    // actions may depend on non-existent headers from stale .d files.  We need
    // to allow the action to proceed to execution in this case.)
    reporter.removeHandler(failFastHandler);
    // doesn't exist
    Artifact in = createSourceArtifact("in");
    Artifact out = createDerivedArtifact("out");
    registerAction(new TestAction(TestAction.NO_EFFECT, Collections.singleton(in), Collections.singleton(out)));
    try {
        // fails with ActionExecutionException
        buildArtifacts(amnesiacBuilder(), out);
        fail();
    } catch (BuildFailedException e) {
        assertThat(e.getMessage()).contains("1 input file(s) do not exist");

Example 12 with TestAction

use of com.google.devtools.build.lib.actions.util.TestAction in project bazel by bazelbuild.

the class TimestampBuilderTestCase method createActionButton.
