Simple test runner to use in ESM modules.
After trying to use jest with an esm module for so long i just gave up and made this module. This module will scan for every .test.js or .spec.js file in current workspace and try running them. You can limit scanning into one directory by passing in the dir name like this:
-
C:\myapp> estest- Scans C:\myapp -
C:\myapp> estest dist- Scans C:\myapp\dist
npm i -D @efekos/es-test- Create a test script to run estest:
"estest"(Also createpretestto compile if you use TypeScript) - Write some tests
- Run
npm test
import {describe,it,inst} from '@efekos/es-test/bin/testRunner.js' // You excplicitly have to import from testRunner.js i have no idea why
import {expect} from 'chai' // or any other assertion module
describe('9 + 10',()=>{ // create a suite with describe
it('should be 21',()=>{ // create a test with it
expect(9+10).to.be.equal(21);
});
});
function isNumber(s){
return /[+-]?\d+(\.\d+)?/.test(s);
}
describe('isNumber function',()=>{
it('should match all the numbers',()=>{
inst(()=>{ // Create different cases with inst
expect(isNumber('5')).to.be.equal(true)
});
inst(()=>{
expect(isNumber('455.34')).to.be.equal(true)
});
inst(()=>{
expect(isNumber('-145')).to.be.equal(true)
});
inst(()=>{
expect(isNumber('-3465.0000000003')).to.be.equal(true)
});
inst(()=>{
expect(isNumber('-.3495')).to.be.equal(true)
});
inst(()=>{
expect(isNumber('+.25')).to.be.equal(true)
});
},true /*this true makes this test a cased test*/);
});import {onError} from '@efekos/es-test/bin/testRunner.js'
onError('CustomError',(err)=>{ // Handle custom error types
return {
passed:false,
expected:err.exp,
actual:err.act,
formatMode:'none' // 'str' will make every difference in actual value look red instead of making it completely red in summary
}
})
