Examples with CppComponent org.gradle.language.cpp.CppComponent used on opensource projects

Example 1 with CppComponent

use of org.gradle.language.cpp.CppComponent in project gradle by gradle.

the class CppUnitTestPlugin method configureTestSuiteWithTestedComponentWhenAvailable.

private void configureTestSuiteWithTestedComponentWhenAvailable(Project project, DefaultCppTestSuite testSuite, DefaultCppTestExecutable testExecutable) {
    CppComponent target = testSuite.getTestedComponent().getOrNull();
    if (!(target instanceof ProductionCppComponent)) {
        return;
    }
    final ProductionCppComponent testedComponent = (ProductionCppComponent) target;
    final TaskContainer tasks = project.getTasks();
    testedComponent.getBinaries().whenElementFinalized(testedBinary -> {
        if (!isTestedBinary(testExecutable, testedComponent, testedBinary)) {
            return;
        }

        // Setup the dependency on the main binary
        // This should all be replaced by a single dependency that points at some "testable" variants of the main binary
        // Inherit implementation dependencies
        testExecutable.getImplementationDependencies().extendsFrom(((DefaultCppBinary) testedBinary).getImplementationDependencies());
        // Configure test binary to link against tested component compiled objects
        ConfigurableFileCollection testableObjects = project.files();
        if (target instanceof CppApplication) {
