系统测试和集成测试的区别
系统测试:
在开发软件或应用产品时,在最后阶段通过组合所有产品模块进行整体测试,这称为系统测试。进行此测试的主要目的是它必须满足客户/用户要求规范。它也被称为端到端测试,就像在开发结束时执行的那样。该测试不依赖于系统实现;简而言之,系统测试人员不知道实现了过程和面向对象中的哪种技术。
该测试分为系统的功能性和非功能性需求。在功能测试中,测试类似于黑盒测试,它基于规范而不是所使用的编程语言的代码和语法。另一方面,在非功能测试中,它通过生成相应编程语言的测试用例来检查性能和可靠性。
集成测试:
该测试是软件模块的集合,其中还测试了不同组件之间的关系和接口。它需要在一次将组成组件集成在一起的项目级活动之间进行协调。
集成和集成测试必须遵守构建计划,以便在早期阶段定义集成和识别错误。但是,与系统测试员不同,集成商或集成测试员必须具备编程知识。
系统测试和集成测试的区别:
S.No. | Comparison | System Testing | Integration Testing |
---|---|---|---|
1. | Basic | Tests the finished product. | Validates the collection and interface modules. |
2. | Performed | After integration testing | After unit testing |
3. | Requires | Understanding of the internal structure and programming language. | Knowledge of just interlinked modules and their interaction. |
4. | Emphasis | On the behavior of all module as a whole. | System functionalities interface between individual modules. |
5. | Covers | Functional as well as non-functional tests. | Only functional testing. |
6. | Test cases | Created to imitate real life scenarios. | Build to simulate the interaction between two modules. |
7. | Approaches | big-bang, incremental and functional. | Sanity, regression, usability, retesting, maintenance and performance tests. |
8. | Executed | Only by test engineers. | By test engineers as well as developers. |
