Automated test platform (13): interface automation framework and platform comparison, application scenario analysis and design ideas sharing

One 、 Preface

The traditional solution to realize interface automation is to build an automation framework , adopt excel Write use cases to drive execution , For example, the common combination of the jack of all trades technology stack ：openpyxl、pytest、allure etc. .

Many companies use automation frameworks rather than test platforms to automate interfaces , The main reason is that the construction cost of automation framework will be much lower than that of test platform . But for the maintenance of automated use cases 、 And the difficulty of writing use cases . The cost of building architecture is inversely proportional to the cost of maintaining use cases , So we need to choose whether to build an automation framework or a testing platform according to the actual situation . When the business is in fast iteration , The project more 、 When the scene is complex , The inefficiency of use case cost maintenance will make automation more and more difficult and complex , At this time, it is better to build a test platform than an automation framework . conversely , You should choose the automation framework .

Why is it said that the automation framework is difficult to maintain ？ Take a simple question ： When interface parameters are changed , How to find out the test cases affected by it ？

This problem is absolutely intractable for the traditional automated framework testing scheme , The biggest single project I have ever handled is 2000 Multiple interfaces , The use cases based on this are 10000 strip +, If you pass excel It is difficult to have an appropriate and efficient solution to the problem of driving interface automated testing . If you do it through the platform , Because of the concept of database , Interface maintained id And the relationship before the use case , You only need to query the data associated with the changed interface in the use case to directly find out the scope of influence .

This is just a small example , In fact, there are many places that hinder the development of traditional interface automation testing . So many large companies will build automated test platforms , To improve the efficiency of automation , Improve the maintainability of use cases .
