One of the most important step in software engineering is software testing. Proper software testing will dramatically reduce the risk during software implementation. By the end of the day, testing will ensure your stakeholder about the quality of your software. When you find a bug, you will assign a task to developer to fix it. When the developer has fixed the bug, it will be reassigned back to you. When you find another bug, you and the developer will do it again and again. Bad news is, when your program is fixed in one part, sometime it will make trouble in other part. Sometime what you have found as bug and then fixed, it will be bug again when the developer works in another part or your software. Thus, we have to do thorough testing for each release to ensure that no bugs are re-introduce. Isn't it boring? Yes, doing repetitive task (especially if the developer make daily release) will be boring. Thus, we need to automate our testing. You can do automation with any softwa...

I love coding, especially Java. Because Android apps is written in Java, I would love to make one as well. Unfortunately, when I tried to install Android Studio on my Ubuntu yesterday, I got this error message: 'tools.jar' seems to be not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE. When I google on this error, there are so many websites and forums discuss about this error as well as the solutions. However, in linux (or ubuntu in my case), sometime we have different environment so that the solution will not always work (sometimes we have to do another thing before or after that solution). And this also happen in this case. Here are what I did then: 1. Know what exactly the problem is: the problem is that the JAVA_HOME in my system did not point to JDK. Instead, it points to a JRE. JRE can only be used to run java applications, not to build them. 2. Check the java path used by the system. In terminal, I typed the following: ...
