node.js - Do hooks in Mocha run regardless of test failures?

Question

Just like the title says. Do before/after/beforeEach/afterEach hooks in Mocha work even if tests fail?

Answer 1

是的，即使测试失败，它们也会运行。但是，如果您使用 bail 选项运行 Mocha，则拆解挂钩将不会运行。

只是在这里对现有的测试套件进行了快速检查。
编码：

setup(function() {
    console.log("1");
});
teardown(function() {
    console.log("2");
});

处决：

D:\Dev\JS\toposort>mocha


  Toposort
    ◦ should sort correctly: 1
    √ should sort correctly
2
    ◦ should find cyclic dependencies: 1
    1) should find cyclic dependencies
2
    ◦ #2 - should add the item if an empty array of dependencies is passed: 1
    √ #2 - should add the item if an empty array of dependencies is passed
2


  2 passing (15 ms)
  1 failing

  1) Toposort should find cyclic dependencies:
     AssertionError: expected [Function] to not throw 'Error' but [Error: Cyclic dependency found. '3' is dependent of itself
.] was thrown
