Jest Testing Suite

Jest killed any enthusiasm I had for testing in iOS codebases and offered a surprisingly focused set of APIs which really do make testing a delight. To really understand Jest, I started vscode-jest which aimed to tightly integrate your tests into your editor.

Things I Like

• The care and effort into all of the matchers
• Snapshots, and especially inline Snapshots
• How parallel test suite ordering works

Notes

• How I do [[tests/testing-js]]
• I enjoy inline snapshot tests [[tests/inline-snapshots]]
