Software testing companies should employ the fail-fast principle in their Software Development Lifecycle (SDLC) process because when your program fails, you can quickly fix the errors and promptly move to the next. Ideally, systems shouldn't fail, and your application shouldn't crash, but when it does, you should prevent frequent recurrences.
You are bound to err on the project, and the software will end up with a couple of bugs. System failures and software crashes are frequent, and deadlocks, data loss, privacy corruption, and inconsistency is particularly bad. The fail-fast principle prompts us to quickly fail early on in the process because if an error occurs, then it is easier to fix. It is better if the software fails immediately instead of later where you need to work around the failure. Since fail-safe makes errors appear earlier in the SDLC and bugs found are simpler to reproduce and cheaper to fix, it is an ideal situation to be in as it helps stabilize your software. Ensure there are fewer bugs and defects when it goes into production, therefore resulting in superior quality and launch-ready products. Fail-fast is a cost-effective method of application testing and a principle behind many agile practices.
Here are cases in software development when you need to employ fail-fast testing:
You write tests and cover all types of test case scenarios in which they may fail and highlight all the requirements that need to be met before implementation in a test-driven development method.
Developers are required to employ a method of continuous integration for current works with a shared repository, and it needs to be verified by automated builds to help the team to find and fix bugs early.
Instead of typically starting up the system or using the fall-back strategy if the system fails or stops due to missing environment variables and start-up parameters, you should be notified immediately to fix the issue.
Software theory usually prescribes one of two extremes to ensure quality. First is granting sole responsibility to an individual on the team; this removes accountability from the rest of the team. Second is the need to collaborate on everything that translates to follow the pack mentality. At Codoid, we suggest an alternate option, train, and educate all team members to become decision-makers on the project. Make sure this combined theory is put to the test by ensuring everyone is equally responsible for the outcome of the product quality. Let customers be empowered to make the right decision. Enunciate to your team the long-term consequences of their choices and explain how it affects user experience.
Providing software testing services can be hard for many companies. Yet, we are confident in our capability of predicting what may happen, and we take time to explain the possible outcome. We ensure that we get things done without having to give up the power of decision making. It is a risky gamble, but our work speaks for itself, take a look at our testimonials, and you'll see we're right.
