Performance of unit testing Angular app

I'm loving Angular, but running unit tests on Karma gets my nerves. It's too slow for me.

In this post, I explain mechanics under Angular's testing module and how to improve the performance.

What makes my tests slow?

To evaluate Angular unit testing performance I captured the CPU profiling with running Karma.

Plain JavaScript objects are better than classes when they can be used, and many popular modern frameworks have adopted their use.

Consider that in React a component can be created as either a class or as an object.

// using a class
class Welcome extends React.Component {
  render() {
 Hello, {this.props.name}

In your local clone of your forked repository, you can add the original GitHub repository as a "remote". ("Remotes" are like nicknames for the URLs of repositories - origin is one, for example.) Then you can fetch all the branches from that upstream repository, and rebase your work to continue working on the upstream version. In terms of commands that might look like:

Add the remote, call it "upstream":

git remote add upstream https://github.com/whoever/whatever.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream
