Expected Behavior

nyc report should probably work with nyc@14.1.1 too

Observed Behavior

nyc report does not work with nyc@14.1.1

Troubleshooting steps

• still occurring when I put cache: false in my nyc config

I'm confused, what you've pasted shows that it is reporting. I believe nyc@14 does capture coverage that was missed by nyc 13 so that may be why you are seeing additional branches not covered (because nyc 13 failed to recognize those branches).

Hi,

please note the following difference:

nyc@13.3:

...
gms@orion:~/work/HOT/node-async-context (master)$ npx nyc report --reporter=text-lcov
TN:
SF:/home/gms/work/HOT/node-async-context/src/asyncctx/ContinuationLocalStorage.ts
FN:56,(anonymous_0)
FN:271,(anonymous_1)
FN:59,(anonymous_2)
...
a.s.o

nyc@14.1.1:

...
gms@orion:~/work/HOT/node-async-context (master *)$ npx nyc report --reporter=text-lcov
gms@orion:~/work/HOT/node-async-context (master *)$

strange that this happens with all my repos using Jasmine-TS, but not with the repo using Mocha / TS-Node. But nyc report should work independently of the test runner, should it?
Another observation: if I capture the coverage with nyc@14; then after installing nyc@13 without capturing coverage again, I am getting the result from nyc report

this issue does not occur using nyc@15.0.0-beta.0 ( #1104 )

[coreyfarrell]

Ah the issue is that you have -e .ts when you execute but not when you ran reports in a separate command. nyc@14 runs the include/exclude processing when generating reports and unfortunately did not include the extension .ts by default. This means that for nyc 14 you would need npx nyc report -e .ts --reporter=text-lcov. nyc 15 will fix this by adding .ts to the default extension list.

works in nyc 15
