子测试

测试上下文的 test() 方法允许创建子测试。 此方法的行为与顶层 test() 函数相同。 以下示例演示了如何创建具有两个子测试的顶层测试。

test('top level test', async (t) => {
  await t.test('subtest 1', (t) => {
    assert.strictEqual(1, 1);
  });

  await t.test('subtest 2', (t) => {
    assert.strictEqual(2, 2);
  });
});

在本示例中，await 用于确保两个子测试均已完成。 这是必要的，因为父测试不会等待子测试完成。 当父测试完成时仍然未完成的任何子测试将被取消并视为失败。 任何子测试失败都会导致父测试失败。

The test context's test() method allows subtests to be created. This method behaves identically to the top level test() function. The following example demonstrates the creation of a top level test with two subtests.

test('top level test', async (t) => {
  await t.test('subtest 1', (t) => {
    assert.strictEqual(1, 1);
  });

  await t.test('subtest 2', (t) => {
    assert.strictEqual(2, 2);
  });
});

In this example, await is used to ensure that both subtests have completed. This is necessary because parent tests do not wait for their subtests to complete. Any subtests that are still outstanding when their parent finishes are cancelled and treated as failures. Any subtest failures cause the parent test to fail.
