@Test public void HelloAppEngine_test() { String result = HelloAppEngine.getInfo(); assertThat(result) .named("HelloAppEngine.getInfo") .containsMatch("^Version:\\s+.+OS:\\s+.+User:\\s"); }
@Test public void helloInfoTest() { String result = HelloAppEngine.getInfo(); assertThat(result) .named("HelloInfo.getInfo") .containsMatch("^Version:\\s+.+OS:\\s+.+User:\\s"); }
@Test public void helloInfoTest() { String result = HelloAppEngine.getInfo(); assertThat(result) .containsMatch("^Version:\\s+.+OS:\\s+.+User:\\s"); }
