We often hear that a certain framework is used, but what exactly is it? What are the advantages and features of the framework?
What is an automation framework
The automation framework is a tool that includes the organization, execution, monitoring, and reporting of automated tests. It is a tool set composed of multiple tools, libraries, modules, and APIs. The goal of an automation framework is to enable testers to quickly write, execute, and maintain automated tests. Through the automation framework, testing efficiency is improved, manual testing costs are reduced, and software quality is improved.
Advantages of automation frameworks
-
• Provides a set of reliable testing tools and methods that can improve testing accuracy and consistency.
-
• The automation framework has detailed reports and logs to help us clearly view results and locate problems.
-
• Through the automation framework, we can quickly write and execute test scripts to improve testing efficiency.
-
• The automation framework can be integrated with other development tools and processes to provide more comprehensive test coverage and continuous integration capabilities.
Testing framework components
-
• Test driven framework
-
• Programming scripting language
-
• Data management functions
-
• Reporting and logging functionality
-
• Custom and third-party plug-in module management
-
• Continuous integration capabilities
test driven framework
Test-driven framework is the main part of automated testing. Commonly used testing frameworks include JUnit, TestNG, Pytest, etc. Test-driven frameworks generally provide the infrastructure for test case execution, including the management and execution of test cases, as well as the collection and reporting of results.
现在我也找了很多测试的朋友，做了一个分享技术的交流群，共享了很多我们收集的技术文档和视频教程。

procedural scripting language
Programming scripting language is the core technology of the automation framework. Currently commonly used automated test script languages include Python, Java, etc. Using scripting languages for automated testing allows testers to write various customized test cases based on their business. Scripting languages usually provide a variety of libraries and modules related to automated testing, such as Requests, jsonpath, json, re, etc. For everyone to use flexibly.
Data management functions
The data types we need during the testing process are managed according to different functions. Commonly used ones include configuration data, parameterized data, result data, etc. We need to consider how we manage this data.
-
• Configuration data/global parameters: Most of these are saved in the project configuration file, such as execution environment, database information, log configuration, etc.
-
• Parameterized data: Generally, projects have a separate data management module. Currently, the popular ones include Excel, yaml, database, number-making platform, etc. The decision is made based on the current situation of the framework, team and project.
-
• Result data: This general interface is to store it in a file or database for later data viewing and analysis.
Reporting and logging functionality
A detailed visual report will be generated after the automated test is executed. Through this report, we can easily understand the execution of this test and the final execution results. If there are failed use cases in the report, we can confirm the specific cause of the failure by consulting the logs. Therefore, a complete execution report and detailed log information constitute two important components of our framework. Their existence enables us to locate and solve problems efficiently and accurately.
Custom and third-party plug-in module management
When some functions of our framework are not satisfied, we need to implement some implementations or re-encapsulate them based on existing functions to make them simpler and meet the current business.
-
• Custom modules: Commonly used BasePage, BaseApi, email, corporate WeChat, logs, file operations, image recognition and other related tool classes. We often encapsulate some tool classes in our framework to make it easier for those who use the framework.
-
• Third-party plug-ins: For example, when generating test reports, we will generate them in HTML format. Common ones are Allure reports, loguru logs, Selenium, Appium modules, etc.
Continuous integration capabilities
The key to achieving maximum value from our automated test cases is their application in high-frequency usage scenarios. Currently, CICD has been widely used by most companies in the product development process. Therefore, our framework needs to have easy-to-docking features, which will enable our automated testing to exert greater value and further improve efficiency and effectiveness.
Finally, I would like to thank everyone who read my article carefully. Looking at the increase in fans and attention, there is always some courtesy. Although it is not a very valuable thing, if you can use it, you can take it directly!
Software Testing Interview Document
We must study to find a high-paying job. The following interview questions are from the latest interview materials from first-tier Internet companies such as Alibaba, Tencent, Byte, etc., and some Byte bosses have given authoritative answers. After finishing this set I believe everyone can find a satisfactory job based on the interview information.
