Example 1 with SkylarkRuleContext

use of com.google.devtools.build.lib.rules.SkylarkRuleContext in project bazel by bazelbuild.

the class SkylarkRuleImplementationFunctionsTest method testCreateSpawnActionCreatesSpawnAction.

@Test

    SkylarkRuleContext ruleContext = createRuleContext("//foo:foo");
    createTestSpawnAction(ruleContext);
    ActionAnalysisMetadata action = Iterables.getOnlyElement(ruleContext.getRuleContext().getAnalysisEnvironment().getRegisteredActions());
    assertThat(action).isInstanceOf(SpawnAction.class);
}

Example 2 with SkylarkRuleContext

use of com.google.devtools.build.lib.rules.SkylarkRuleContext in project bazel by bazelbuild.

the class SkylarkRuleImplementationFunctionsTest method testCreateSpawnActionShellCommandList.

@Test
public void testCreateSpawnActionShellCommandList() throws Exception {
    SkylarkRuleContext ruleContext = createRuleContext("//foo:foo");
    evalRuleContextCode(ruleContext, "ruleContext.action(", "  inputs = ruleContext.files.srcs,", "  outputs = ruleContext.files.srcs,", "  mnemonic = 'DummyMnemonic',", "  command = ['dummy_command', '--arg1', '--arg2'],", "  progress_message = 'dummy_message')");

Example 3 with SkylarkRuleContext

use of com.google.devtools.build.lib.rules.SkylarkRuleContext in project bazel by bazelbuild.

the class SkylarkRuleImplementationFunctionsTest method testCreateTemplateActionWithWrongEncoding.

/**
   * Simulates the fact that the Parser currently uses Latin1 to read BUILD files, while users
   * usually write those files using UTF-8 encoding. Currently, the string-valued 'substitutions'
   * parameter of the template_action function contains a hack that assumes its input is a UTF-8
   * encoded string which has been ingested as Latin 1. The hack converts the string to its
   * "correct" UTF-8 value. Once {@link com.google.devtools.build.lib.syntax.ParserInputSource#create(com.google.devtools.build.lib.vfs.Path)}
   * parses files using UTF-8 and the hack for the substituations parameter is removed, this test
   * will fail.
