Soft assertions in javascript

I have two backend projects P1 & P2. Data from P1 has to flow into P2 after some processing via a middleware. I am writing this middleware and I have to create an E2E testing module.

I will have 100s of test cases and in each there may be 3 or 4 expect statements. The chai 'expect' function is a form of hard assertion. How can I get soft assertions in javascript. Basically, the test case will run all 3 or 4 expect statements and report which one's failed.
