If necessary, have local normalization/sanitization functions to replace things that are noisy or unstable, like timestamps or error stacks. Always prefer `toThrowMatchingInlineSnapshot()` over naked `toThrow()` or `toThrow()` with a regex. ### Test Organization Tests are in `src/test` ### Mocking HTTP Requests We use `msw`. We use v2 so don't use the v1 api. ### File I/O Use node-fixturify against a temp directory. Do not mock file system operations. Set XDG variables like XDG_DATA_HOME, XDG_STATE_HOME, XDG_CONFIG_HOME &c. so that files are written to the temp directory. IMPORTANT: when setting an XDG variable be sure to call `Logger.reset`. The logging utilities use a singleton that only checks for the XDG directory on initialization. Be sure to call `Logger.reset` in `afterEach` and not in `beforeEach` so you don't poison future tests. Here are the usage docs from fixturify's README ```js const fixturify = require('fixturify') const obj = { 'foo.txt': 'foo.txt contents', 'subdir': { 'bar.txt': 'bar.txt contents' } } fixturify.writeSync('testdir', obj) // write it to disk fixturify.readSync('testdir') // => deep-equals obj fixturify.readSync('testdir', { globs: ['foo*'] }) // glob support // => { foo.txt: 'foo.text contents' } fixturify.readSync('testdir', { ignore: ['foo*'] }) // glob support // => { subdir: { bar.txt: 'bar.text contents' } } fixturify.writeSync('testDir', { 'subdir': { 'bar.txt': null } }) // remove subdir/bar.txt fixturify.readSync('testdir') // => { foo.txt: 'foo.text contents' } fixturify.writeSync('testDir', { 'subdir': null }) // remove subdir/ ``` ```js const fixturify = require('fixturify') const obj = { 'subdir': { 'foo.txt': 'foo.txt contents' }, 'emptydir': {} } fixturify.writeSync('testdir', obj) // write it to disk fixturify.readSync('testdir', { ignoreEmptyDirs: true }) // => { subdir: { foo.txt': 'foo.txt contents' } } ``` Keep in mind that we always use ESM and always write in TypeScript, so convert the usage appropriately.
