JUnit继续在预期的异常之后断言 [英] JUnit continue to assert things after expected exception

问题描述

我有一些类似

@Test(expected = IllegalArgumentException.class)
public void cdIntoNonExistantFolder() {
    cdTool.changeDirectory("nonexistant");
    assertThat(cdTool.getStatusCode(), not(equalTo(0)));
}

我相信 assertThat 不运行为 changeDirectory 将抛出异常。有可能使它仍然运行吗？

I believe the assertThat does not run as changeDirectory will throw the exception. Is it possible to make it still run?

推荐答案

我宁愿在单元测试中避免任何try / catch结构。以下是 Catch-Exception 的一种可能性：

I'd rather avoid any try/catch structures in unit-tests. Here's one possibility with Catch-Exception:

@Test
public void cdIntoNonExistantFolder() {
    catchException(cdTool).changeDirectory("nonexistant");

    assertThat(caughtException(), instanceOf(IllegalArgumentException.class));
    assertThat(cdTool.getStatusCode(), not(equalTo(0)));
}

或JUnit 5：

@Test
public void cdIntoNonExistantFolder() {
    expectThrows(IllegalArgumentException.class, () -> {
        cdTool.changeDirectory("nonexistant");
    });

    assertThat(cdTool.getStatusCode(), not(equalTo(0)));
}
