Welcome to EZtek’s Blog!
Today we are talking about software quality. Read this article to know the best practices of maintaining the software quality that the EZtek team follows during product development for our customers. On our channel, we share thoughts on recent developments in the tech industry, follow us to never miss new Blogs.
We need to measure quality to check if the software solution satisfies its requirements. The requirements can be classified as functional or non-functional, read our comparison of Functional vs Non-functional requirements for more details.
Types of Software Quality Metrics
Product Quality Metrics
They regulate how the software should perform both from the client and server sides.
This group includes such components as:
- Reliability
- Performance
- Security
- Maintainability.
Code Quality Metrics
In fact, it is difficult to create code quality metrics. Still, we at EZtek think that good code written according to the coding standards is: Readable, Reusable and Well-documented.
So, the criteria for measuring code quality include:
- Number of lines
- Static code analysis
- Software complexity metrics as complex code is more difficult to maintain.
- Testability
- Portability
- Reusability.
How to prevent quality issues?
- Static code analysis
It examines the code without launching it and checks it according to the coding standards. - P2P Reviews
We use git and bitbucket for version control and remote repository management. When the feature is completed, the teammates act as code reviewers. - Reviews by senior or lead developers.
Main Software Test Metrics
- Mean time to detect: These metrics show how much time it will take to discover the issue.
- Mean time to repair: It shows how much time the organization will need to fix the issue.
- Test reliability: refers to the percentage of tests that provide helpful feedback
- Code coverage: is the percentage of the code base that has been covered by testing.
- Test coverage: This metric helps make sure that we use various types of tests to assess the product, not only unit tests.
- Escaped defects found: shows the number of defects found in production
- Defect distribution: Here we assess the bugs according to different criteria, severity, area of the application, testing type, etc
Best practices for improving the code quality
- Use a coding standard: It makes sure everyone uses the same coding style, improves the consistency and readability of the code.
- Commenting and documenting: help other developers understand your code better.
- File and folder organization
- Manual code review
- Refactor legacy code: It will help to clean up the application code and make it easier to maintain.
