It writes to the GitHub PR and emails reports so devs get an integrated view of their current workflows. Setting it up was easy because it uses conventional code coverage formats. We use it on every PR.

It generates good quality reports and provides me with the detailed result of the code coverage in the tests I am performing which helps me optimize the code for the areas not covered in tests too. I primarily use it for CPP and it works very well for it (have tried it with Javascript and works for it also). At last, it serves the purpose of its creation and helps you build a code with less bugs.

I am using Codecov in my current job role, as I have developed test suite, I am using to generate report of code coverage. I like the ease of useability of the product. I am integrating it with my development environment, & parallely checking code coverage. I am using since last one year, on daily basis I am interacted with product. I like the report generation, as per our need we can generate report as a output of development. I can easily implement it & that's why I am using it in my work. I needed customer support for few reasons, I went to the official website & I am totally sastisfied with the customer support. I am still using it in my work, thanks to Codecov team for a good product.
