I discovered an issue that appears to be caused by caching. On the initial run of a test, it evaluates the test and determines that it fails (without errors), however on subsequent runs, I get: Cannot find module './emptyFunction' from 'node_modules/jest-cli/.haste_cache/preprocess-cache/warning_764896bb1571a8dbaa5c10886672e1b1.js':

I will demonstrate that in the following command line log. The first run is a subsequent run (not initial). I then reinstall jest-cli to remove caching and rerun the jest at which I get no errors. I then run it again and get the error.

$ jest "components/__tests__/Logs-test.js"

Setting preprocessCachingDisabled to true fixes the above issue. But that's a workaround.

I have a same issue too.

I was debugging awhile, haste_cache logic may be related to this issue.
When a cacheKey is generated in readAndPreprocessFileContent(filePath, config) function of utils.js, a different value is made every time.

A. First try
Filename : /Users/KimCoding/Workspace/PhotoMoa/src/sample/__tests__/helloworld-test.js
cacheKey : 754124e15ac50f241d7079bd992b0814

B. Second try
Filename : /Users/KimCoding/Workspace/PhotoMoa/src/sample/__tests__/helloworld-test.js
cacheKey : f57f35f2fd451dad8fe33658d2a4eda1

Because I'm using the babel-jest plugin, it is in the doubt.

Yeah I think the problem is that it stringifies the config object as well and the encoding isn't stable, ie. the keys in the config object are sorted randomly. I'm not sure why that would lead to problems however, it just leads to more work for the pre-processor. But yeah, this should be fixed.
