How many times have you had this conversation?

"Hey, the project doesn't run on my machine any more."

"Have you tried running npm install?"

...pause...

"Yeah, that fixed it, thanks"

Execution order of Jest/Jasmine test code

While tests run in source order, surrounding code does not which can lead to hard to debug issues.

Compare the test file below with the sample output below that and note the order of the log messages.

Key points

Any code not inside of it, beforeAll, afterAll, beforeEach or afterEach runs immediately on initialisation.
This means code at the end of your file runs before even your before hooks.

Shows a list of all node processes and lets you select which one you want to debug.

For example

$ debug.sh
1) 73428 node webpack/webpackDevServer.js
2) 73494 node build/dist/server.js

Select which process to debug: █

Test case

Bug when running Testcafe on Slate Editor inputs in Chrome/Safari

Serve index.html on port 8080, e.g. http-server
Run test, e.g. testcafe chrome test.js

Expected

New text is appended to input

Actual

Demo showing that by specifying a resolver for a scalar property, you can override the value.

This is useful for authorization as it means you can centrally check permissions per field. Your general resolvers can return whole objects without caring about which fields the current user may or may not be allowed to see.
