Four examples of automated testing models and their advantages and disadvantages
1. Linearity test 1. Concept: A linear script generated by recording or writing the steps corresponding to the application. Simply to simulate the user’s complete operation scenario. (operations, repeated operations, data) all mixed together. 2. Advantages: Each script is relatively independent and does not generate other dependencies or calls. 3. Disadvantages: The development cost is […]
Analysis of the advantages and disadvantages of six methods of packaging Python code (recommended collection)
Python is a high-level programming language that is easy to learn, easy to use, and cross-platform, so it has been widely used in development. However, Python code needs to be run in the Python interpreter, which may be inconvenient for some users. As an interpreted language, Python makes the source code public upon release. Although […]
