JaCoCo Pros and Cons

We can verify how many lines of code is executed and how many lines of code is not executed in unit testing.We can make sure our bussiness logic is working as expected.

We are able to get the details of the code which is not tested then we can test those missed lines of code also by writing better Unit Test scenarios. Review collected by and hosted on G2.com.

For Legacy Project implementing Jacoco plugin is tough nut to crack, beacause all modern project flows this approach,but not the legacy one.

It don''t provide complete details of code coverage like code smell,code bugs in the java code other than that it is a good tool for Code Coverage. Review collected by and hosted on G2.com.

The most alluring aspect of JaCoCo is its capacity to offer thorough code coverage analysis. It provides comprehensive insights into the efficacy of test cases with support for line, branch, method, and instruction-level coverage.

It's impressive how accurately JaCoCo measures code coverage. It accomplishes this without significantly increasing performance overhead, ensuring my tests run quickly.

Its accessibility during development is improved by integrating with well-known Integrated Development Environments (IDEs), like Eclipse and IntelliJ IDEA. Review collected by and hosted on G2.com.

For legacy codebases with low or no test coverage, integrating JaCoCo presents challenges. Understanding and addressing existing gaps in test coverage require additional effort, especially in large and complex codebases. Review collected by and hosted on G2.com.

It can be easily integrated with Eclipse, STS and IntelliJ IDE Review collected by and hosted on G2.com.

I did not find anything wrong in the JaCoCo, it is the best plugin to check the code coverage Review collected by and hosted on G2.com.

As it is in the name Ja(va) Co(de) Co(verage) says, it is a java library that's mainly used in the testing phase, wherein its used to check the code coverage of each line of code written. Review collected by and hosted on G2.com.

There's nothing as such to dislike in it, but one thing that can be improved is the UI of the generated report as I feel it can be modernized a bit. Currently it seems to be a little retro. Review collected by and hosted on G2.com.
