Using Metrics to Improve Software Testing

Filed Under: Automated Software Testing, Metrics
Read Full Article

Metrics are a useful tool for evaluating the health, quality, and progress of an automated software testing effort. Metrics can also be used to examine past performance, current status, and future trends. Without metrics, it would be almost impossible to quantify, explain or demonstrate quality. Metrics also help demonstrate return on investment (ROI). As once quoted… Read more »

Automated Testing Metrics: Impact on Software Quality

Posted On:
Filed Under: Metrics
Read Full Article

Metrics can aid in improving automated testing processes and tracking the status of such efforts. While we don’t recommend that metrics alone drive the automated software testing process, they can certainly enhance it. Carefully defined metrics offer objective, measurable factors by which to assess a testing effort. The better the testing effort is, the better… Read more »

Defect Density – Automated Software Testing Metric

Posted On:
Filed Under: Metrics
Read Full Article

Metrics are an important factor when evaluating the effectiveness of an automated software testing effort. Defect density is another well known metric. (See previous blogs on other testing metrics). Defect density is a measure of the total known defects divided by the size of the software entity being measured. This software entity could be a subset or component of the… Read more »

Percent of Automated Software Testing Test Coverage

Another automated software testing metric we want to consider is Percent of Automated Testing Test Coverage.  That is a long title for a metric to determine how much test coverage is the automated testing actually achieving?  It is a metric which indicates the completeness of the testing. This metric is less focused on measuring how… Read more »

Is your “Defect Leakage” out of control?

Read Full Article

Much has been reported in the news lately about several high-visibility software systems– e.g. commonapp.org, healthcare.gov, united.com, etc.– whose extensive defect leakage affects many. We calculate defect leakage in software systems as follows: the number of high priority defects found in the production phase, divided by the number of high priority defects found in the testing phase, multiplied by 100….

Continuing in our discussion of metrics that can be applied to testing processes, Automation Progress is another useful metric. It refers to the percent of automatable test cases and asks the question, “How many test cases have been automated at a given time?” Basically, this metric evaluates how well one is doing in the goal… Read more »

Percent Automatable

Read Full Article

At the beginning of an automated software testing effort, the project is either automating existing manual test procedures, starting a new automation effort from scratch, or some combination of both. Whichever the case, a percent automatable metric can be determined.  Percent automatable can be defined as: of a set of given test cases, how many… Read more »

In the previous blog on metrics dated August 29,  we mentioned that one of the characteristics of a good metric is simplicity.  Albert Einstein once said, “Make everything simple as possible, but not simpler.”  When applying this wisdom towards automated software testing, you will see that: Simple reduces errors Simple is more effective Simple is elegant… Read more »

What Is A Metric?

Read Full Article

Metrics can aid in improving your organizations automated software testing process and tracking its status. If you can measure something, then you have something you can quantify. If you can quantify something, then you can explain it in more detail and know something more about it. If you can explain it, then you have a better chance to attempt to improve upon it, and so on... Read More »

Improving with Metrics Metrics can aid in improving your organization’s automated testing process and tracking its status.  It was once stated: “When you can measure what you are speaking about, and can express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your… Read more »
