Some of the teams that claim to be doing “Agile” aren’t. Compressing the schedule, throwing out the documentation, and coding up to the last minute is not Agile. Agile methods are above all sustainable. Agile teams really do need testers, but they don’t need is QA acting as a Quality Police. Nine Principles for testing…

Log-File locations There are several directories where logs (including those from crashes) might appear – not all of them are standardized (i.e. some may be ROM-specific). Some examples are: /data/anr “Application Not Responding” files /data/dontpanic seems to be a standard location (AOSP), and contains some crash logs including traces /data/kernelpanics /data/panic/panic_daemon.config may point to other locations configured…
There are three main types of Exceptions: Checked Exceptions, Runtime Exceptions, Errors. Checked Exceptions have to be handled by the code. These represent avoidable exceptional conditions which can be handled and recovered from. Runtime Exceptions need not be handled by the code. These represent unexpected exceptional conditions which can be handled but not necessarily recover from. Errors need not be handled…
Why write Test Cases? The big reason for doing test cases in advance is to give you more time to think about the feature. The creative juices take a bit of time to get flowing and having the application in front of you with the clock running towards the release is not conducive to that.…
