My code coverage report shows 100% covered source code. However, I would expect less because there is only one test file (FooPage.spec.js
) covering one (FooPage.vue
) of two components. The second component (BarPage.spec.js
) is shown in the report but not considered in the coverage metrics. I would have expected to see BarPage.ts
reported as red with 0/4 statements covered (instead of 0/0).
I guess, the instrumentation with nyc
does not work as expected with the all
option.
See https://github.com/toaditoad/code-coverage-mwe for a reproducible example.
See https://github.com/istanbuljs/nyc/issues/1415 with same question as well.
See Readme of my updated working example for a (not so nice) workaround to add all source files as additional entries in Cypress' webpack preprocessor: https://github.com/toaditoad/code-coverage-mwe
This only works for Cypress 6.x but raised as request for Cypress 7.x which does not support the webpack preprocessor: https://github.com/cypress-io/cypress/issues/17230
