What you'll learn

- Perform code refactoring more often, ridding it of legacy, thanks to the guarantees that tests give
Description
The market-leading programming processes includes automated testing as a key component. The only trustworthy method for verifying that the code is functional is through tests. They do not eliminate bugs, but they do enable you to maintain a manageable amount of them. Tests provide assurance that changes made to one component of the system would not harm other parts.
This course looks at both general test writing principles and contemporary JavaScript testing tools.
