Data servers 7 Steps to Improving Your Data Testing

When you have tens of thousands of rows of data, how do you know what to test or how much to test? A set percentage? Random test cases? When do you stop testing? It can be overwhelming. Here are seven steps to help your team streamline their data testing efforts and know what to test, how much to test, and when to stop testing.

Pencil to paper Document Why as Well as What: Finding the Purpose of Your Software

Code can express what we want to accomplish, but it’s a little more difficult to express why we’re doing something in the first place. The people who maintain code are often not those who originally wrote it, so documenting why helps set a context and gives clues as to what the author was thinking when they came up with a particular design, making developers' jobs easier.

Magnifying glass Exposing False Confidence in Your Tests

Testing can't tell you what's wrong with your code. It can only show what is not wrong with it. And though we cannot possibly conceive everything that might be wrong, it's important to stray from the "happy path." We need test cases that present bogus inputs and assert that they raise exceptions. That's how we can replace our false confidence with true assurance.

Weak link in a chain The Problem with How We Do Regression Testing

Current approaches to automated UI testing are broken because regression testing is not testing; regression testing is version control of the behavior of the system. The goal is functional consistency. The regression test ensures that, after a change to the software, the unchanged parts still work the same as before. This realization makes creating and maintaining tests much more efficient.

Jack-o'-lantern 3 Scarily Easy Testing Tips

In the “spirit” of Halloween, here are three scarily easy testing tips that will help you find defects in your software under test. These tips will help you easily test an app's power usage, search for a particular term in a dynamically generated URL, and verify a form's checkbox has a checkmark. After all, it’s our job as testers to make sure using our software is a treat, not a trick.

4 steps in a QA process 4 Strategies for a Structured QA Process

Being a software tester is no longer just about finding bugs. It is about continuous improvement, defining a clear test strategy, and going that extra mile to improve quality. Following a consistent, structured approach to QA will help you acquire more knowledge about the product you are testing, ask questions you otherwise may not have thought of, and become a true owner of quality.

Bug taxonomy Using Bug Taxonomy to Design Better Software Tests

In software testing, bug taxonomy involves defining feature categories and collecting lists of possible bugs in each category. These lists can be used to give inexperienced testers some starting points, to help experienced testers brainstorm new ideas, and to evaluate the completeness of a test case. Using an existing bug taxonomy can be useful, but creating your own is even better.

Metrics dashboard on a tablet For Great Performance, Rethink Your Load Testing

The word concurrency is often used to define workload for load testing, as in concurrent users. Too often, it's the only input defined. In reality, there are a number of factors that contribute to workload and affect concurrency, and they all contribute to your load testing abilities—and, ultimately, the performance of your product.
