Example 46 with TestExternsBuilder

use of com.google.javascript.jscomp.testing.TestExternsBuilder in project closure-compiler by google.

the class IntegrationTest method testSubstituteEs6Syntax.

@Test
public void testSubstituteEs6Syntax() {
    CompilerOptions options = createCompilerOptions();
    CompilationLevel.ADVANCED_OPTIMIZATIONS.setOptionsForCompilationLevel(options);
    options.setLanguageIn(LanguageMode.ECMASCRIPT_NEXT_IN);
    options.setLanguageOut(LanguageMode.ECMASCRIPT_NEXT);
    externs = ImmutableList.of(SourceFile.fromCode("testExterns.js", new TestExternsBuilder().addConsole().build()));
    // This is a regression test to confirm both that SubstituteEs6Syntax switches to object
    // literal shorthand here and that it correctly reports that it has added that feature.
    // IntegrationTestCase runs `ValidityCheck` to report an error if a feature usage gets added to
    // the AST without that addition being recorded.
    test(options, // 
    "console.log({console: console});", "console.log({console});");
