Testing

• Test files use *_test.cpp suffix, named after the class under test.

Test structure pattern

using namespace testing;
using namespace testing::ext;

namespace OHOS {
namespace Rosen {
class MyFeatureTest : public testing::Test {
public:
    static void SetUpTestCase();
    static void TearDownTestCase();
    void SetUp() override;
    void TearDown() override;
};

void MyFeatureTest::SetUpTestCase() {}
void MyFeatureTest::TearDownTestCase() {}
void MyFeatureTest::SetUp() {}
void MyFeatureTest::TearDown() {}

HWTEST_F(MyFeatureTest, TestSomething, TestSize.Level1)
{
    EXPECT_EQ(result, expected);
    ASSERT_NE(ptr, nullptr);
}

Running a single test binary

Each ohos_unittest target in test/unittest/BUILD.gn produces its own binary. Target names follow the pattern <module>_<test_name>:

Module	Build target
wm	wm:test
wmserver	wmserver:test
dm	dm:test
dmserver	dmserver:test
dm_lite	dm_lite:test
window_scene	window_scene:test
snapshot	snapshot:test
extension/window_extension	extension/window_extension:test
