Karma unit testing webpack:API fatal error handler returned after process out of memory

I am trying to execute karma unit test cases for my project. When I run the whole test cases which are available in the application, it is failing with the below error. But when I configure to run fewer test cases by executing all the controllers in a folder, it works. How to increase the memory size to execute all the test cases.

Tried searching but couldn't get any working solutions. Any guidance would be helpful.`

$ karma start karma.conf.js


#
# Fatal error in , line 0
# API fatal error handler returned after process out of memory
#
/c/Users/AB18082/AppData/Roaming/npm/karma: line 14: 20164 Segmentation fault      node "$basedir/node_modules/karma-cli/bin/karma" "$@"

EDIT 1:

When i try to increase size

$ node --max_old_space_size=10240 node_modules/karma/bin/karma start karma.conf.js

Cannot get stack trace in GC.
FATAL ERROR: NewSpace::Rebalance Allocation failed - process out of memory

EDIT 2:

After setting those node --max_old_space_size=4096 changes my application itself is not loading now. tried uninstalling the nodejs and cleared

Now getting these error when i start the application also.

FATAL ERROR: Committing semi space failed. Allocation failed - process out of memory
1: 00BF287E
2: 00FD3013
3: 00FD1B24
4: 00FD16FC

EDIT:3

After so much googling able to fix loading the application using the below cmd and still the testing is having the same issue.

env NODE_OPTIONS=--max_old_space_size=2048 node node_modules/webpack/bin/webpack

Your issue will resolve once you do changes in package.json like below

"scripts": {
  "test": "node --max_old_space_size=4096 ./node_modules/karma/bin/karma start ./test-config/karma.conf.js",
  "test-ci": "node --max_old_space_size=4096 ./node_modules/karma/bin/karma start ./test-config/karma.conf.js --single-run",
  "test-coverage": "node --max_old_space_size=4096 ./node_modules/karma/bin/karma start ./test-config/karma.conf.js --coverage"
 }
