Report Karma failures as soon as they occur, exiting and reporting the the first failure instead of waiting for all of the tests to run.
Multiple test failures can often be the result of a single piece of erroneous code, therefore it is not always necessary to run and produce the results of every single test.
Failing fast is an important concept of the Agile software development methodology as it allows the learning process to begin as early as possible, providing the shortest feedback loop available for the developer to begin fixing a failing test.
npm install --save-dev karma-bail-fast
Either pass the bail-fast reporter as a command line argument:
karma start --reporters bail-fast
Or add the reporter to your karma.conf.js file:
// karma.conf.js
module.exports = function (config) {
config.set({
reporters: ['bail-fast']
});
};
