Install Mocha and Chai into the development dependencies of a Node.js project, and then configure the ESLint environment to prevent false positives.
- [Instructor] We've been discussing the tools in theory…around writing tests.…Let's apply that knowledge to our project.…Three steps are necessary for installation.…The first thing we need to do…is use npm to install mocha and chai…to the project's devDependencies.…Then we'll edit package.json…to add the definition for the test script,…which will be mocha.…Finally we're going to have to add…an ESLint environment configuration for mocha globals.…This isn't required,…but it will prevent a number of false positives.…
We'll do that by adding an ESLint configuration…to the test directory.…Let's switch over to Adam.…- [Adam] Open up a terminal,…and make sure you're in the project directory.…We're going to use npm to install mocha and chai…to the devDependencies.…So, dash capital D, and press return.…After a moment,…mocha, chai, and other dependencies will be installed.…Next, do the tree view,…select package.json.…
In the script section,…add a comma after start,…then a definition for test.…Which will be just in double quotes,…
