Top benefits of tracking software testing metrics include the following:. Some of the most common software testing metrics that can be used for both automation and for software testing in general are given below. These are useful in the broader spectrum of software testing. The general software testing metrics are divided into the following three categories:. The principle of coverage metrics is to communicate to all stakeholders about what is covered during formal testing.
The dimensions include validation points to evaluate application in compliance with the requirements and weigh them by business quality. The two types of Coverage Metrics include:. This metric determines how defects are identified and created by evaluating the compliance with agile principles. The dimensions include the number of defects identified in different stages of software cycle and also the number of defects created in different stages of Software cycle. This is one of the important areas where we focus to minimize production leakage.
Pareto Chart is one of the standard analysis techniques, used to identify the main types of defects that have been identified so far.
A Release Burndown chart can help you understand, across an entire software release, how development is progressing, how much of the planned software functionality remains to be done, and when you can expect the release to be completed. It shows that over four sprints the team has reduced the number of stories to be done from 43 to 26, and predicts that the release will be completed in 7 more sprints.
This metric checks, per release or product component, how many bugs or issues were identified after the software was already in production. This is a good indication of quality as perceived by the end user. We call this metric true test coverage as opposed to the regular test coverage metric, which only measures unit tests. This is a metric that tells you how much of your codebase or feature set is covered by all types of tests—unit, integration , UI automation, manual tests and end-to-end acceptance tests.
It can reveal quality gaps—parts of the software that are new or actively used but do not have sufficient test coverage. In our list of metrics above, you might have noticed that True Test Coverage is a new one which you might find difficult to compute on your own. In complex software projects with millions of lines of code and numerous test frameworks, collecting the data for a holistic test coverage metric is a major challenge.
This is where Quality Intelligence technology comes in—tools that provide visibility for development managers, by monitoring tests across all test frameworks, collecting test execution data, and correlating it with data about code changes and frequently used features.
This can help compute a True Test Coverage metric which can expose quality gaps in a software product. Productivity can be considered as a function of the value and the cost. Each can be decomposed into different measurable size, functionality, time, money, etc. Different possible components of a productivity model can be expressed in the following diagram.
The quality of any measurement program is clearly dependent on careful data collection. Data collected can be distilled into simple charts and graphs so that the managers can understand the progress and problem of the development. Data collection is also essential for scientific investigation of relationships and trends. Quality models have been developed for the measurement of quality of the product without which productivity is meaningless.
These quality models can be combined with productivity model for measuring the correct productivity. These models are usually constructed in a tree-like fashion. The upper branches hold important high level quality factors such as reliability and usability. Data Structures. Operating System. Computer Network.
Compiler Design. Computer Organization. Discrete Mathematics. Ethical Hacking. Computer Graphics. Web Technology. Cyber Security. C Programming.
Control System. Data Mining. Data Warehouse. Javatpoint Services JavaTpoint offers too many high quality services. Classification of Software Metrics Software metrics can be classified into two types as follows: 1. Types of Metrics Internal metrics: Internal metrics are the metrics used for measuring properties that are viewed to be of greater importance to a software developer. Advantage of Software Metrics Comparative study of various design methodology of software systems.
