does this point make sense?

[high trail]

When you increased code coverage, what was the previous value? You could rephrase the bullet to:

Increased code coverage from X% to 80% by using Jenkins and TypeScript to configure build server deployment to reject commits with inadequate tests

Notice how the main selling point (you increasing code coverage by a measurable amount) is in the first few words of the bullet point. People reading your resume may only have a minute to skim through it, so putting the juicy quantitative details right at the beginning of each bullet point makes it more likely to be noticed

I guess the secret for each bullet point is to phrase it like

What you did, aka the result, (include some quantifiable information like a percentage or amount) + how you did it

Oh yeah I see what you mean by contradictory....Did removing the inadequate tests allow for more adequate tests to be created?

How did removing the bad tests allow for code coverage to increase?

Yeah i don't know which is better, tbh lol. But a lot of people have told me to include the result first lol

You could rephrase the bullet to

Increased code coverage from X% to 80% by using Jenkins and TypeScript to configure build server deployment to only include new test files with 80% or more coverage or something idk
