09/10/2021, 6:57 AM@Ross Coundon do you know how can I ignore some folders from jest?
Adrián Mouly
09/10/2021, 6:57 AMI mean, I have a monorepo, and don’t want to test the frontends in this case.

Ross Coundon
09/10/2021, 6:59 AMIn your jest.config.js you can set values for
Copy code
testMatch: ['**/test/**/*.it.ts?(x)', '**/test/**/*.test.ts?(x)'],a
Adrián Mouly
09/10/2021, 7:18 AMI see.
Adrián Mouly
09/10/2021, 7:18 AMI don’t have config file, just using default.
Adrián Mouly
09/10/2021, 7:18 AMGoing to need to add one then.

Ross Coundon
09/10/2021, 7:23 AMIn case it's useful, we have this which targets our unit test and integration tests (the it.ts files)
Copy code
module.exports = {
preset: 'ts-jest',
testEnvironment: 'node',
testPathIgnorePatterns: ['.d.ts', '.js'],
testMatch: ['**/test/**/*.it.ts?(x)', '**/test/**/*.test.ts?(x)'],
moduleNameMapper: {
'@/(.*)$': '<rootDir>/src/main/$1',
},
moduleFileExtensions: ["ts", "tsx", "js"],
collectCoverage: false,
collectCoverageFrom: ['src/main/**/*.{js,ts}'],
};a

09/10/2021, 7:32 AMNice.
Adrián Mouly
09/10/2021, 7:32 AMIs there a jest config in TS?
Adrián Mouly
09/10/2021, 7:32 AMI don’t use any JS.

Ross Coundon
09/10/2021, 7:55 AMI suspect so but haven't bothered. We're all TS too but as this is basically static I've never bothered to investigate

10/19/2021, 6:58 PM@Ross Coundon will adding my own
jest.config.js Copy code
module.exports = {
testEnvironment: 'node',
testMatch: ['**/__tests__/test_cases/**/*']
}t

10/19/2021, 6:59 PM^ I'm reworking sst's jest integration today
thdxr
10/19/2021, 6:59 PMIn the meanwhile you can just call jest directly

arda
10/19/2021, 7:02 PMyou are indeed!
arda
10/19/2021, 7:05 PM@thdxr in case you might be interested. I find using jest directly would get me into
SyntaxError: Cannot use import statement outside a modulesst testt
thdxr
10/19/2021, 7:08 PMI don't use babel actually - I use esbuild-runner highly recommend it
thdxr
10/19/2021, 7:08 PMlet me find my config
thdxr
10/19/2021, 7:09 PMWe'll probably switch to it as the default when I make these updates
thdxr
10/19/2021, 7:09 PMinstall
esbuild-runnerthdxr
10/19/2021, 7:09 PMand then this is the config:
Copy code
module.exports = {
roots: ["<rootDir>/test"],
testMatch: ["**/*.*test.(ts|tsx|js)"],
transform: {
"\\.ts$": "esbuild-runner/jest",
},
}a
arda
10/19/2021, 7:13 PMstill hitting this..
t
thdxr
10/19/2021, 7:15 PMMy transform limits it to just
.ts.jsa
arda
10/19/2021, 8:03 PMstill no luck

thdxr
10/19/2021, 8:07 PMhm ok I'll look into this once I start my jest fiddling
