…#7665) Added missing `npm run test` invocation to align with our typescript [test](https://github.com/aws/aws-cdk/blob/master/packages/aws-cdk/test/integ/init/test-typescript.sh#L27).
Couple of things here: **require.cache** In version `v25.5.0`, jest introduced an [implementation](jestjs/jest#9841) of their own to the `require.cache` object. It seems that it doesn't handle caching `json` modules properly, which causes our code to fail because `mod.paths` is `undefined` when we are querying for `json` files that were required (for example `package.json` or `cloud-assembly.schema.json`). https://github.com/aws/aws-cdk/blob/07fe642e38118e24837b492fa182737fc41bb429/packages/%40aws-cdk/core/lib/private/runtime-info.ts#L66 ```console TypeError: Cannot read property 'map' of undefined ``` The "fix" was to add a null check to prevent failure when looking up modules who don't have the `paths` property defined. Note that this was only observed in test environments using `jest > v25.5.0`, not during actual runtime of `cdk synth`. This is because `jest` manipulates the built-in `require` module of `nodejs`. **graceful-fs** In version `v25.5.0`, jest [added](jestjs/jest#9443) a dependency on the `graceful-fs` package. The version they depend on (`4.2.4`) differs from the version that we bring (`4.2.3`). This caused the `graceful-fs` dependency that comes from `jest` no to be deduped by node at installation. In turn, this caused multiple copies of the library to be installed on disk. The `graceful-fs` package monkey patches the `process.chdir` and `process.cwd` functions with a cached version for better performance. For reasons not completely clear to us, the existence of multiple copies of the module, caused `process.cwd()` to return incorrect cached results, essentially always returning the directory that the process was started from, without consideration to calls to `process.chdir`. This broke `decdk` (and possibly many more) tests which rely on `process.chdir`. Fixes #7657
