Testing a Java application on Windows without Windows

Java is supposed to be “write once, run anywhere” but in practice, there are always platform differences that can and do result in bugs. For that reason, and because in general it’s a good idea to test as much as possible, it’s nice to run tests (even for Java applications) on multiple platforms. As evidence … Continue reading Testing a Java application on Windows without Windows →

Even the most trivial “Hello World” demo program relies on a compiler, (most likely) a standard library, and then all of the low level system services, such as the operating system, drivers, and hardware. In any of those areas, it’s pretty much certain … Continue reading The Importance of Upstreaming Issues →
