When using Jest, I like to bump the global coverage threshold. Yesterday I was excited to bump the numbers in my suggest-test repository.
coverageThreshold: {
global: {
branches: 67,
functions: 33,
lines: 38,
statements: 38,
},
},
After testing 4 not large units, my branch coverage was much higher than everything else. The reason this made me happy is that it was the result of using my own suggest-test
tool on itself. The includeStatements
command line argument had honed in on conditionals for me.
suggest-test --includeTested=false --includeStatements=false
I think it's a mistake that so many focus on statements/lines and not more on conditionals/branches. Conditionals are where most of the business logic resides. And it's easy to write half baked tests to boost statement coverage without really testing much.
And while it's still only a release candidate, feel free to try out my @clowd/suggest-test NPM package.
