I'm performing mocha tests on my React components that I wrote using ES6 syntax. I'm using Istanbul to do code coverage tests. When i set my NODE_ENV to 'test`, I get the following output:
----------|----------|----------|----------|----------|----------------|
File | % Stmts | % Branch | % Funcs | % Lines |Uncovered Lines |
----------|----------|----------|----------|----------|----------------|
All files | Unknown | Unknown | Unknown | Unknown | |
----------|----------|----------|----------|----------|----------------|
As can be seen, it says unknown for everything. When I remove the NODE_ENV variable, it works fine. What can I do to run this test in the above environment?
