Unable to mock CodePipeline
Summary
I am trying to mock calls to CodePipeline.putJobSuccessResult in a Lambda. However, a real aws-sdk call is being made instead of invoking my stub. I am successfully able to mock out some other services such as DynamoDB and DocumentClient using the same technique, but not CodePipeline.
Versions Jest: 24.7.1 aws-sdk: 2.447.0 aws-sdk-mock: 4.5.0
Example
my.js:
import * as AWS from 'aws-sdk';
exports.handler = async event => {
const { ['CodePipeline.job']: { id: jobId } = {} } = event;
if (jobId) {
await new AWS.CodePipeline({ apiVersion: '2015-07-09' })
.putJobSuccessResult({ jobId })
.promise();
}
return { message: 'Done!' };
};
my.spec.js:
import * as AWSMock from 'aws-sdk-mock';
import * as AWS from 'aws-sdk';
describe('My spec', () => {
beforeAll(() => {
AWSMock.setSDKInstance(AWS);
});
it('Invokes CodePipeline if job ID present', async () => {
const successStub = jest.fn().mockResolvedValue(null);
AWSMock.mock('CodePipeline', 'putJobSuccessResult', successStub);
const jobId = 'yesh';
const event = { ['CodePipeline.job']: { id: jobId } };
await lambda.handler(event);
expect(successStub.mock.calls[0][0]).toEqual({ jobId });
AWSMock.restore('CodePipeline', 'putJobSuccessResult');
});
});
Result:
ValidationException: 1 validation error detected: Value at 'jobId' failed to satisfy constraint: Member must satisfy regular expression pattern: [0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}

....
The stack trace shows that it is invoking the actual aws-sdk library, not the mock.
