describe(title, fn)it test cases.The describe function groups related test cases under a common title.
it(title, fn)The it function defines an individual test case.
assert(expression, [title])true or false.The assert function evaluates a given expression and logs the result. If the expression is true, the test passes; otherwise, it fails with an optional message.
assert.strictEqual(item1, item2, [message])The assert.strictEqual function checks if item1 and item2 are strictly equal (===).
assert.deepStrictEqual(obj1, obj2, [message])The assert.deepStrictEqual function checks if two objects are deeply equal, comparing their properties recursively.
it.skip()The it.skip function is a placeholder that allows you to skip a test case.
it.only(title, fn)The it.only function allows you to run only a specific test case or group of test cases, ignoring others.
runTests()The runTests function runs all the test cases defined using describe and it. If it.only was used, only those specific tests will run.
Test results are displayed in the browser's DOM. Successful tests are marked in green, and failed tests are marked in red. The detailed error messages are displayed under the failed tests.
