2022-06-24 06:09:57Truth and falsehood

When it comes to embedded software testing, maybe you are new , But in the era of intelligent Internet of things , People will pay more and more attention to embedded software testing .

Speaking of embedded software testing , Let's quickly understand the characteristics of embedded software . Embedded software is real-time 、 Limited memory space 、I/O Less channels , And low power consumption is required 、 high reliability , It is also sensitive to cost , Strong correlation with hardware , Therefore, the testing of embedded software is quite different from that of general commercial software .

   The environment of embedded software development and operation is completely different , It's separate. , Development in Windows/Mac OS Desktop client ( Host environment ) on , The running environment is on the target machine environment , That is, it is generally based on Linux/Android Embedded operating system developed by kernel or like RT-thread Such a real-time operating system , Support ARM CPU、 MCU and Bluetooth chip and other key hardware with low power consumption .

The unit test of embedded software is generally carried out in the host environment , Only in individual cases ( For example, the target compiler may be defective ) It will be required to perform... In the target environment , So in unit testing , The difference between embedded software and general commercial software is relatively small , however , The unit test of embedded software requires high code quality , General requirements MC/DC coverage .

Integration testing of embedded software , It generally refers to the integration with the hardware environment of the target machine , It can also be integrated with the simulation environment , At this time, we need to do the corresponding hardware compatibility test . But when it comes to system testing 、 Configuration item test or validation test , Generally, it will be executed in the target environment , At this time, it is quite different from the test of general commercial software . Due to the real-time performance of embedded system , The real-time response of the system shall be fully considered in the test , Its response time is generally required to be in the millisecond level , The corresponding load test is indispensable . When testing the target machine , Generally, the code compiled on the host computer needs to be instrumented . In this way, when the target machine executes the program , Return the predicted data during pile insertion to the host for analysis , therefore , The data transmission between the host and the target should also be taken seriously .

besides , We need to formulate the reliability level and security level that meet the system requirements , Carry out corresponding reliability test and safety test . Embedded software testing tools , There are few open source tools , Mostly business tools , And often in complete sets , Cover system functions 、 Performance analysis and safety testing . Today, we will introduce the commonly used or easy-to-use embedded software testing tools , There are mainly :

  1. ETest Studio
  2. Klocwork
  3. Hitex TESSY
  4. Rapita Verification Suite
