Encountered an issue with running tests in vscode-test - runTests function throwing

Setting up tests for my vscode extension for the first time and encountering an issue.

I copied and pasted the example from code.visualstudio's /working-with-extensions/testing-extension.

However, I'm facing an error when trying to call runTests:

error TS2345: Argument of type '{ extensionDevelopmentPath: string; extensionTestsPath: string; }' is not assignable to parameter of type 'TestOptions | ExplicitTestOptions'.
  Object literal may only specify known properties, and 'extensionDevelopmentPath' does not exist in type 'TestOptions | ExplicitTestOptions'.

Here is the code snippet causing the error:

import * as path from 'path';

import { runTests } from 'vscode-test';


async function main() {
    try {
        const extensionDevelopmentPath = path.resolve(__dirname, '../../../');

        const extensionTestsPath = path.resolve(__dirname, './suite/index');

        await runTests({ extensionDevelopmentPath, extensionTestsPath });

    } catch(err) {
        console.error('Failed to run tests.');
        process.exit(1);
    }
}


main();

Looking for assistance in identifying the mistake. Appreciate any help provided.

Answer №1

The proper method can be found here :

async function main() {
    try {
        let testOptions = { extensionDevelopmentPath: path.resolve(__dirname, '../'), extensionTestsPath: path.resolve(__dirname, './suite/index') };
        // Get VS Code, extract it, and execute the integration test
        await runTests(testOptions);
    } catch (error) {
        console.error('Failed to execute tests');
        process.exit(1);
    }
}
