Is Debugging Necessary Before Deployment?
Debugging is a multi-dimensional process and involves many layers. It requires special set of expertise for software engineers to conduct debugging tests in software. When debugging tests are conducted on an application, comprising several subsystems, the process becomes more complex as change in one may affect the other. In that case, it requires a comprehensive approach to test and check for all possible loopholes.
Debugging varies in terms of complexities, scopes and attributes. It may range from fixing simple error as well as running programming codes and collecting data to check performance at different stages, analyzing and scheduling updates. Stability and performance of an application depends large on the abilities of testing engineers. The thorough debugging process is conducted; the better will be the performance of the application.
The process of debugging is affected by several factors namely - complexities of the system and to some extent, on the choice of programming language. Testing engineers use an array of debugging tools that help them in indentifying errors more easily amongst thousands of lines of codes. A debugger, as debugging tools are collectively called, allows the developer to test and check execution of the application for any erratic behavior under different circumstances and highlight errors as and when occur.
Typically debugging is a process that involves reproducing the error under constrained circumstances. The techniques involved are mentioned as below.
- Print debugging
- Remote debugging
- Post-mortem debugging
- Wolf-fence algorithm
- Debugging and deploying
Debugging and deployment
Software deployment is the final stage of development when the application is installed at client's end-at client's software ecosystem. It is generally carried out in phases that can happen either at producer's end or client's end or both simultaneously.
Since every client environment is unique and so applications deployment needs to be customized according to specific requirements.
Debugging is an important part of deployment that can happen right before or after release. Release is the final stage that signifies completion of development work. During this process the software is transferred to customer's end. Before the application is finally deployed, a series of debugging activities take place to ensure that the software runs smoothly in client environment.
The stages involved in the process of deployment are mentioned as below.
- Release -Post development, the application is released at customer's environment. It involves taking stock of infrastructural requirements and necessities.
- Installation and activities - Installing and setting up commands for execution of the application.
- Deactivation -It is terminating software on client's end.
- Synchronization - The process involves modification of the software to fit into customer's enterprise application environment.
- Update - Update is about replacing an old version of software with a new, upgraded version.
