It made headlines for all the wrong reasons when it launched on October 1, but things could have been so different for the HealthCare.gov website if only it had been tested properly before release. Users trying to enroll encountered all sorts of glitches, including very slow page updates, "page not found" errors and frequent crashes. Early server outages were blamed on an unexpectedly high volume of traffic as nearly 5 million Americans tried to access the website on day one, but it soon emerged that serious flaws existed in the software, and the security was not properly assessed or signed off. According to CBS, the security testing was never completed. Fox uncovered a testing bulletin from the day before the launch that revealed the site could only handle 1,100 users "before response time gets too high." The Washington Examiner revealed, via an anonymous source, t... (more)

Software Testers Too Need a Black Box

Recording and maintaining good evidence of testing is growing more important all the time. The ability to document what actually happened during the development of hardware or software is vital in many industries. Medical equipment is a great example, as any failure could lead to unexpected complications or even death. In the event that this occurs, auditors must be able to review the original manufacturing process and track the usage and maintenance of the machine during its lifecycle. Evidence of testing importance can be neatly summed up by considering the difference between ... (more)

Quality Assurance: The Most Undervalued Piece of Devops

Software works the way it was designed because of a group of downtrodden, undervalued and unsung heroes. Often dismissively described as testers, these champions of precision can be more accurately termed Quality Assurance. They set the bar high and work hard to ensure that the software you buy is easy to use and efficient. Without their expertise you would encounter a lot of inaccessible, bug-ridden releases. QA is frequently undervalued by software developers. It is often seen as an unnecessary expense - a drain on time and resources. The truth is that finding and fixing bugs... (more)

Making a Case for a Test Case

For software testers to create a detailed test case during the QA process can be tricky: sometimes it's not an option; sometimes it's wasted effort. Here are ways to help make that decision. Part of the skill set required to be a good tester involves the ability to assess a software project and decide when it's worth putting in the effort to create really detailed test cases. Sometimes the software will lend itself to unstructured testing, sometimes the development methodology will dictate a specific approach, and sometimes every possible facet will need to be covered. If you pl... (more)
