what is slow parameter in mocha?

Question

When we define mochaOpts in Protractor, we define one parameter as slow. I do not understand what is the use of that parameter. I tried changing it's value but I can't see any change in test execution time.

mochaOpts: {
   reporter: 'spec',
   slow: 1000,
}

Answer 1

According to the documentation its used for testing

-s, --slow

Specify the "slow" test threshold, defaulting to 75ms. Mocha uses this to highlight test-cases that are taking too long.

To tweak what's considered "slow", you can use the slow() method:

describe('something slow', function() {
  this.slow(10000);

  it('should take long enough for me to go make a sandwich', function() {
    // ...
  });
});
