focha

Mocha wrapper that runs previously failed tests first Failing mocha = Focha

Install

Requires Node version 6 or above.

npm install --save-dev focha

Use

Avoid running all tests just to check if previously failed tests are fixed. If tests fail, focha saves file .focha/.focha.json. On the next run, focha will only run tests listed in this file. Thus the best strategy is to let focha run failing tests and then, if it succeeds let it run all the tests.

You can do this by running it twice. From your CI file execute the second command using && and pass --all flag to run all the tests.

$(npm bin)/focha src/*-spec.js && $(npm bin)/focha --all src/*-spec.js

or simple use NPM script in package.json

{
  "scripts": "focha src/*-spec.js && focha --all src/*-spec.js"
}

If the first command finds nothing, or failing tests pass, the second command will run all the tests. If the failing tests are still failing, the second command will not execute.

Service

Instead of local JSON file, focha can save and load failed tests in a REST API, just pass the end point via SERVER variable. Example service implementation bahmutov/test-results-server.

configuration

SERVER url of the remote server that receives and returns failed tests
API_KEY for this client on the server

Debug

Run with DEBUG=focha environment variable

Example

See example project focha-test with its test history

.travis.yml shows how tests are setup
TravisCI build history where you can see
- a failing test run #4
- the next run #5 just executes the single failing test first
- the run #6 has the problem fixed and runs failing test and then all tests

rocha - randomizes tests in Mocha to find inter-test dependencies
