Is this personal taste, or has it to do with the scope of the projects these guys are working on?
1. the ability to run everything (a.k.a the whole project) using the preferred SCM (or build tools)
for example: mvn clean install
where your pom.xml already set to have cobertura (code coverage), checkstyle/pmd (linting/style/formatting), and findbugs (static code analysis)
2. the ability to run a very specific unit-test somewhere deep down in your project via your IDE as you're writing code (the IDE compiles your code on the fly...) and get everything I mentioned above :)
for example: I want to run one new unit-test for a new code => I don't have to drop to my console/command-line/terminal to run mvn clean install. I just go to my unit-test, highlight the method name, run it through eclipse/intellij and I get everything.
