测试：
测试是验证和确认软件或应用程序没有错误、满足其设计和开发指导下的技术要求并通过处理所有异常和边界情况有效和高效地满足用户要求的过程。
调试：
调试是修复软件错误的过程。它可以定义为识别、分析和消除错误。此活动在软件无法正确执行后开始，并以解决问题和成功测试软件结束。它被认为是一项极其复杂和乏味的任务，因为在调试的所有阶段都需要解决错误。
以下是测试和调试之间的区别：
| Testing | Debugging |
|---|---|
| Testing is the process to find bugs and errors. | Debugging is the process to correct the bugs found during testing. |
| It is the process to identify the failure of implemented code. | It is the process to give the absolution to code failure. |
| Testing is the display of errors. | Debugging is a deductive process. |
| Testing is done by the tester. | Debugging is done by either programmer or developer. |
| There is no need of design knowledge in the testing process. | Debugging can’t be done without proper design knowledge. |
| Testing can be done by insider as well as outsider. | Debugging is done only by insider. Outsider can’t do debugging. |
| Testing can be manual or automated. | Debugging is always manual. Debugging can’t be automated. |
| It is based on different testing levels i.e. unit testing, integration testing, system testing etc. | Debugging is based on different types of bugs. |
| Testing is a stage of software development life cycle (SDLC). | Debugging is not an aspect of software development life cycle, it occurs as a consequence of testing. |
| Testing is composed of validation and verification of software. | While debugging process seeks to match symptom with cause, by that it leads to the error correction. |
| Testing is initiated after the code is written. | Debugging commences with the execution of a test case. |
