Benefits of Software Testing Metrics

What is Software Testing Metrics?

Software Testing Metrics is defined as a quantitative measure that is used to estimate the progress, quality, and health of a software testing effort. Metrics can also be characterized as “STANDARDS OF MEASUREMENT”.

Test Metrics Uses-

• To check how many defects exist within the module?
• To check how many test cases are executed per person?
• To check What is the Test coverage Percentage?
• It is used to make the decision for the next phase of activities such as, estimate the cost & schedule of future projects.
• Used to Understand the kind of improvement required to success the project
• Used to take a decision on process or technology to be modified etc.

How might we measure the quality of the Software by utilizing Metrics? 

On the off chance that Metrics are involved in the Project, at that point the definite status of his/her work with legitimate numbers/information can be distributed. 

For example in the Test report, we can distribute:

1. What number of test cases have been designed per requirement?

2. What number of test cases are yet to plan? 

3. What number of test cases are executed? 

4. What number of test cases are passed/failed/blocked? 

5. What number of test cases are not yet executed? 

6. What number of defects are recognized and what is the severity of those defects? 

7. What number of test cases are failed because of one specific defect? 

In view of the above metrics, test lead/project manager will get the comprehension of the beneath referenced key focuses. 

a) Percentage of work finished

b) Percentage of work yet to be finished

c) Time to finish the rest of the work

d) Whether the project is going according to the timetable or slacking? and so on.

Manual test metrics are divided into two classes 

1. Base Metrics- Base metrics are the crude information gathered by Test Analyst during the test case creation and execution 

2. Calculated Metrics- While Calculated metrics are gotten from the information gathered in base metrics. It is normally trailed by the test manager for test reporting purpose 

Based on the project or plan of action a portion of the significant metrics are- 

• Test case execution productivity metrics
• Test case preparation productivity metrics
• Defect metrics
• Defects by priority
• Defects by severity
• Defect slippage ratio

Test Metrics Life Cycle-

Analysis

• Identification of the Metrics
• Define the identified QA Metrics

Communicate

• Clarify the requirement for metric to the stakeholder and testing groupEducate the testing team about the data points to need to be captured for processing the metric

Evaluation

• Capture and verify the data
• Calculating the value of the metrics using the data captured

Report

• Develop the report with an effective conclusion
• Circulate the report to the stakeholder and respective representative take feedback from stakeholder

Conclusion:

The metrics given in this article are significantly utilized for producing the day by day/week by week status report with precise information during test case creation/execution stage and this is additionally valuable for tracking the project status & Quality of the software.
