TL;DR Now that we know the decimal number system, it is time to switch to the binary computer number system. The post is aligned with the Black Box Software Testing…

TL;DR The disadvantage of fix-point decimal number representation is a limited number of significant digits that we can store in memory. That implies that we lose precision. Let’s examine floating-point…

TL;DR In computing, we also need to represent the number fractions. Fixed-point number representation is one way to handle fractions. The post is aligned with the Black Box Software Testing…

TL;DR Back to school! Here we will explain decimal numbers adding algorithm, but tailored for software testers. The post is aligned with the Black Box Software Testing Foundations course (BBST)…

TL;DR In order to become a master of testing data sets, you must be able to explain to any person in the world, how is test data stored and manipulated…

TL;DR Giving constructive critic is the obligation of every tester. You need to have credible facts when you give someone critical feedback. Most importantly, we, as software testers, must accept…

TL;DR What testing makes interesting is that all tests could only provide partial information that might be useful. This sounds like an excuse for inadequate testing. This post will explain…

TL;DR There are cases when the system under test is so complex, so it could only be tested by creating handcrafted oracle or human observation oracle. The post is aligned…

TL;DR Data-driven testing is when you create oracles based on data set with known characteristics. This post will explain what data set with known characteristics is. The post is aligned…
