Two problems that must be understood before you begin:
1. Recording alone is not enough.
2. Not everyone can perform automated testing.
After understanding the previous two questions, I began to learn a tool:
1. Read the help documentation of the tool.
2. Familiar with programming languages
3. participate in online forums
4. Find a small project trainer
5. Look for someone to review the script
6. Some sample codes attached with the tool
Note:
1. If you do not understand the variables and constants, integer and floating point types, functions, and methods, you should re-consider whether to perform automated testing.
2. If you do not understand or want to use loop, while, for, until, and other conditional statements, such as if, switch, and select, you will encounter many problems.
3. If you do not understand classes, objects, functions, and methods, or prefer to use global variables everywhere, it will be difficult for your scripts to adopt object-oriented ideas, and scripts can work, but it is not easy to understand.
4. If you do not like the test process, but do not like development or testing, consider whether or not to start learning automated testing.
