What’s a Mocha suite?

In Mocha, a “suite” is a group of related tests. You can use the describe function to define a suite, and you can nest suites within other suites to create a hierarchy of tests.

Here is an example of a Mocha test suite:

describe('My contract', () => {
  it('should do something', () => {
    // Test code goes here
  });

  it('should do something else', () => {
    // Test code goes here
  });

  describe('when a certain condition is met', () => {
    it('should do something different', () => {
      // Test code goes here
    });
  });
});

In this example, there is a top-level suite called “My contract” that contains two tests. There is also a nested suite called “when a certain condition is met” that contains an additional test. When the tests are run, Mocha will execute them in the order they are defined and report the results.

Suites are a useful way to organize your tests and make it easier to understand the behavior of your code. You can use suites to group tests by functionality, by contract, or by any other criteria that make sense for your project.
