After merging

After you have merged a PR to master, you need to rebuild and publish your changes.

1. Checkout master git checkout master && git pull
2. Use one of the following make publish commands to publish changes:
   • make publish kind=patch - Use this if your change is a bug fix and is backwards compatible.
   • make publish kind=minor - Use this if your change adds new functionality and is backwards compatible.
   • make publish kind=major - Use this if your change is not backwards compatible.

Setup Tests

• In RestEvents, CommandEvents or BackendEvents, add import bindSimulator:
  • import { bindSimulator } from '@mvf/servicer';
• Then use bindSimulator to create a simulate function:
  • export const simulate = bindSimulator(RestEvents);
• In the tests it is then possible to call actions using the simulate function: const result = await simulate(ActionConstant, { headers }, { body });

Success response

const result = await simulate(ActionConstant, { headers }, { body });
result.output.output; // will contain response from Action

Error response

Response with Status code & Error message

const err = await catchAsyncError(async () => {
  await simulate(ActionConstant,{headers},{body});
});

expect(err.status).toBe(400);
expect(err.message).toBe('Error message');

Response with type of error

await expect(simulate(ActionConstant, {headers}, {body})).rejects.toThrow(BadRequestError);
