Understanding Metrics in Software Testing

Introduction-
Measurements are the means by which software quality can be measured, give you confidence in the product. You may consider the product management of these indicators can be quantitative or qualitative. Typically these are the suppliers of the visibility it needs.

Metrics-
Metrics generally fall into a few categories: management (including the process of efficiency) and improved processes. People are often confused about what parameters to use. You can use different values for different purposes. For example, you can have a set of indicators used to assess the output of your test. One metric may be the project management as the number of errors found. Others may be an efficiency measure of the number of test cases written, or number of tests executed in a given period of time.

Ultimately, when you consider the value of a metric, you require to ask if it provides visibility in to the program product's quality. Metrics are only useful if they help you to make sound business decisions in a timely manner. If the relevancy or integrity of a metric cannot be justified, don't use it. Consider, for example, how management analysis & control makes use of financial reports such as profit/loss, money flow, ratios, job costing, etc. These reports help you navigate your business in a timely manner. Engineering metrics are analogous, providing data to help perform analyses & control the development method. However, your engineers may not be the right people to give you the metrics you require to help in making business decisions, because they are not trained financial analysts. As an executive, you require to select what metrics you require & tell your staff to provide them.

For example, the coverage indicators are essential for your team. Coverage is the measure of a certain number of tests. You may have coverage measurement requirements, the numbers of platform coverage, path coverage figures, the coverage figures scenario, or even cover test measurements plan, to name a few. Cam Kaner lists more than 100 types of measures of coverage in his paper "The negligence and performance testing. Before the project started, it is important to agree on how you will measure the test coverage. Obviously, the coverage of a certain type, lower risk associated with that type.

The goal is to choose indicators that will help you understand the status of your product. Choose wisely a handful of these specific indicators for your project type and use to give visibility to what the product is near its release. The test group should be that it provides much useful information with these parameters.

Conclusion-
The metric provided by the tests provide a great benefit for the executive visibility in the maturity and readiness for the release or production, and visibility into the quality of software product development. This enables the effective management of software development process, allowing for clear measurement of the quality and product integrity.
