1. Report Title and Basic Information
-
Title: Clearly labeled as an Embedded Software Testing Report (e.g., “XXX Embedded System Testing Report”).
-
Version Information: Software version under test, hardware platform model, testing tool version.
-
Author: Test lead, engineers involved in testing.
-
Date: Start and end dates of testing.
-
Reviewer: Personnel reviewing the report (e.g., project manager or quality lead).
2. Test Overview
-
Test Purpose: Describe the objectives of the testing (e.g., functional verification, performance testing, stability testing, etc.).
-
Test Scope: List the modules covered by the testing (e.g., communication protocols, sensor drivers, interrupt handling, etc.).
-
Reference Documents: Requirements documents (e.g., “XXX Requirements Specification”), design documents, test plans, etc.
3. Test Environment
-
Hardware Environment: Detailed description of hardware configuration (e.g., MCU model, memory capacity, peripheral interfaces, etc.).
-
Software Environment: Operating system (e.g., RTOS), compiler (e.g., GCC, IAR), emulator (e.g., J-Link).
-
Testing Tools: Static analysis tools (e.g., Coverity), unit testing frameworks (e.g., Unity/CppUTest), hardware testing devices (e.g., oscilloscopes, logic analyzers).
4. Testing Methods and Strategies
-
Test Types:
-
Unit Testing: Testing of individual functions or modules (coverage target must be specified, e.g., statement coverage ≥90%).
-
Integration Testing: Interface testing between modules (e.g., SPI/I2C communication).
-
System Testing: Overall functional testing (e.g., boot time, power consumption testing).
-
Regression Testing: Re-testing after issues are fixed.
-
Testing Methods:
-
White-box testing (code-level testing), black-box testing (functional verification).
-
Dynamic testing (runtime testing), static testing (code review).
5. Test Cases and Results
-
Case Format (in table format):
Case ID Test Item Input Conditions Expected Result Actual Result Pass/Fail Remarks TC-001 Serial Communication Send 0x55 Receive 0x55 Receive 0x55 Pass Baud rate 115200 TC-002 Watchdog Reset Trigger timeout System reset Not reset Fail Need to adjust watchdog feeding cycle -
Key Content:
-
Must include boundary value testing (e.g., memory overflow, extreme temperature conditions).
-
For failed cases, root cause must be noted (e.g., hardware interrupt conflict).
6. Testing Issues and Defect Analysis
-
Defect List:
Defect ID Description Severity (Critical/Major/Minor) Status (Open/Fixed/Closed) DEF-001 ADC Sampling Value Drift Major Fixed -
Issue Analysis: Root cause analysis of key defects (e.g., hardware noise causing ADC errors, need to add software filtering).
7. Testing Conclusion
-
Overall Evaluation: Clearly state whether the testing passed (e.g., “All critical function tests passed, meeting requirements”).
-
Residual Risks: List the impacts of unresolved issues (e.g., “Power consumption exceeds limits in high-temperature environments, needs further optimization”).
-
Release Recommendation: Provide a conclusion on whether it can be released (e.g., “Recommend release, but need to fix minor defects in version V1.1”).
8. Appendix
-
Test Log: Original test data (e.g., serial port logs, memory usage screenshots).
-
Tool Configuration: Test scripts or tool parameters (e.g., Python automation test script snippets).
-
Code Coverage Report (e.g., screenshots of HTML reports generated by LCOV).
Notes:
-
Objectivity: Avoid subjective descriptions, all conclusions must be based on data (e.g., “Reset failure count: 3/1000 times”).
-
Traceability: Each test case must be associated with a requirement number (e.g., Req-ID: RS-002).
-
Version Control: The report must strictly correspond to the software version.
