[Feature]: TSC_COMPILE_ON_ERROR like `ts-node`

[LeoDoldan7]

🚀 Feature Proposal

I need to be able to set TSC_COMPILE_ON_ERROR to true, so jest files run even if I have a TypeScript error somewhere on the codebase.

Motivation

Legacy projects may have a lot of errors, but the role of one developer in particular may be to write the tests (and not to fix the whole codebase). If we don't have this flag, we will have to postpone writing tests until the whole code is fixed.

Example

You can check this https://kulshekhar.github.io/ts-jest/docs/getting-started/options/diagnostics I believe it would fit for your case.

Thanks! Using diagnostic: false fixed my issue.

On a different note, the console is now full of TS warnings. Is there a way of disabling them? I can barely see the result of the tests.

diagnostic: false should not show warning. What is your configuration?

[LeoDoldan7]

Basically this repo with diagnostic: false instead of warnsOnly.

I think it seems to be a bug that it still prints out the warning. You can also use isolatedModules: true which only does transpilation like Babel
