Automated testing

1. Effective automated Testing

• Clearly indicate whether the test results are passed
• No need to install, test or undo any changes made to the environment
• Click Run All Tests
• Full coverage, enough to resolve full coverage is possible

2. Automated testing can be used as a debugging aid

• Code that has been tested automatically is rarely flawed, easy to fix, and allows you to confidently publish software that works correctly.
• Can prevent the introduction of regression

3. Simulation testing, pile testing and other alternative testing techniques

• The pile test is passive and the simulation test is active.
• When trying to reliably reproduce a defect, it is useful to replace the test

Version management System

The source control system is the most important tool you can use in addition to the compiler!

• Stability

Maintain skeleton version stability by creating a branch

• Maintainability

The Create branch is maintained and repaired separately on the skeleton release version.

• Control Branch

Branches often consume a lot of time and managers, so they need to be controlled and used rationally.

Static analysis

It turns out that many flaws can be discovered simply by static checking of the source code, and static analysis can be integrated into the development process to identify problems before they run.

• Make good use of the compiler

The modern compiler has a series of warning messages, such as the Keil compile will prompt a lot of warning messages, to the warning when error handling, to eliminate the warning. Using lint to discover defects in C programs

• Integrate static analysis tools with development tools

Lint can be integrated into the Keil, and there is a dedicated documentation that describes the integration approach.
