I was watching this video in order to learn how to add some simple tests to my Express routes but I am getting all kind of errors while executing a test. The error is:
import * as chai from 'chai';
^^^^^^
SyntaxError: Cannot use import statement outside a module
I have read some similar Stack Overflow questions and GitHub issues but I didn't find a solution for my own application. Finally I found Mocha documentation on GitHub regarding ES modules but it didn't work:
I created the app using TypeScript and CommonJS module to transpile, so I added test: env TS_NODE_COMPILER_OPTIONS='{module: commonjs }' mocha src/test/*.ts to the package.json scripts but I am getting the same error every time. I am using ts-node as a server.
Anyway, this is my tsconfig.json file:
{
compilerOptions: {
sourceMap: true,
target: es6,
module: commonjs,
outDir: ./dist,
rootDir: ./src
},
exclude: [
node_modules
]
}
And this is the src/test/mi-route.ts file:
import * as chai from 'chai';
import * as chaiHttp from 'chai-http';
import server from '../app';
// Assertions
chai.should();
chai.use(chaiHttp);
describe('API Users', () => {
// Test Route GET
describe('GET /api/admin/users', () => {
it('Should return all the users', done => {
chai.request(server)
.get('/api/admin/users')
.end((err, response) => {
response.should.have.status(200);
response.body.should.be.a('object');
done();
});
});
});
});
An this is my package.json scripts:
scripts: {
dev: ts-node-dev src/app.ts,
start: node dist/app.js,
test: env TS_NODE_COMPILER_OPTIONS='{module: commonjs }' mocha src/test/*.ts,
build: tsc -p
},
So... any suggestions? Should I change Common JS Module? Thanks in advance
