Jest is loading the same module twice

[AlokBansal8]

When I try to run multiple test files using jest, I get following error:

 PASS  src/server/gis/common/value-calculator.test.js
 FAIL  src/server/gis/raster/index.test.js
  ● Test suite failed to run

    TypeError: gdal.config.set is not a function
      
      at Object.<anonymous> (node_modules/gdal/lib/gdal.js:58:14)
      at Object.<anonymous> (src/server/gis/raster/index.js:3:39)
      at Object.<anonymous> (src/server/gis/raster/index.test.js:3:14)
          at <anonymous>

But everything works fine if I run only one test file (whichever it may be).

As per node-gdal library's author this is happening because jest is loading the same module twice in the same process.

npm -v --> 5.3.0
node -v --> 8.4.0
jest version --> 20.0.4

Seems like that module has native bindings, so this is probably related: #3552

Yap, duplicate.
