Request: Mocking types for unit test

[Rvice]

Not sure if this is the right place, but it would be nice to get some mock support for unit testing. Is there any plan of this or a recommendation other than writing all the mocks out for jest?

[MrRob]

@Rvice I don't have any plans for unit testing here. I have tried setting up testing in NetSuite a couple of times (using https://www.npmjs.com/package/@oracle/suitecloud-unit-testing and https://github.com/KyleJonesWinsted/suitecloud-unit-testing-stubs) but haven't ever had any luck with it actually being useful. Happy to take a look though if anybody has any ideas for improvement here!

I've tried to set it up too, on the last 3 major projects. Had to abandon it. I'll help out if we can get a baseline going

[Rvice]

I'm close to a baseline with TeamCity, finally got the output working properly and using two tsconfig.ts to separate tests from production code (two different source/output dirs). That way it does not pollute NS with the test code. Issue I'm running into is the mocks with trying to rewrite the example from @oracle/suitecloud-unit-testing in typescript.

Based on what I'm seeing, I see the "stubs" that are in the @oracle/suitecloud-unit-testing, just getting a failure when trying to use those directly on the record.load mock operation.

Happy to help in anyway I can. I know the value, so I'm willing to burn personal time.

[Rvice]

I attempted to "convert" the example from @oracle/suitecloud-unit-testing, but it crashes at record.load.mockReturnValue

I assume this is because my tsconfig is pointing 'N/**' to the HITC defines instead of the suitecloud-unit-testing, but trying to make the swap also doesn't seem to work.

NFT has unit testing - maybe take a look at what's going on there.

[bendemeyer]

I've been able to get unit testing working pretty well by providing my own type declarations for @oracle/suitecloud-unit-testing package. It's mostly just lots of declarations like this:

declare module '@oracle/suitecloud-unit-testing/stubs/log/log' {
    import type logType from '@hitc/netsuite-types/N/log';
    const log: typeof logType;
    export default log;
}

Of course you may want to play around with that module name and your tsconfig path settings/jest moduleNameMapper, but the basic idea should be sound.

I don't know if it would make sense to add something like that to this project, but maybe a separate project that uses this one to provide type declarations for @oracle/suitecloud-unit-testing would be useful.

[ShawnTalbert]

I agree, mocking would make more sense as a separate repo - keep this one focused on what it does best.
