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

Question

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

Answer 1

Yes, they do run even if the test fail.
However, if you run Mocha with the bail option, the teardown hooks will not run.
Just did an quick check with existing test suites here.
The code:
setup(function() {
console.log("1");
});
teardown(function() {
console.log("2");
});
The executions:
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
