Software Testing Basics
Mistakes happen. We may strive for perfection but achieving it is nigh-on impossible. It is therefore critical that we recognise this and embrace it. Know that there is every chance an error will exist in a product we have made. Acknowledge that a program written is very likely to contain some bugs. We must do more than simply realise this; we must do all we can to discover and rectify the situation. Herein lies the basis of software testing basics…
What is software testing?
Essentially, it is a process designed to identify flaws, defects, gaps or missing requirements in a software product. Software testers seek out errors and aim to verify whether or not the expected outcome can be achieved. They do this via both manual and automated techniques and tools, ultimately then reporting their findings to development teams.
Before any product is launched to market, software testing is the vital penultimate step. Evaluation and analysis is key in delivering something reliable to the end customer.
- What are the two main categories of software testing? Functional and non-functional.
- What are the three types of software? System, application and programming language software (broadly speaking).
- Is testing a difficult job? Simply put, yes, due to the fact that no amount of testing will ever result in 100%-bug free software!
Software testing importance
Due to budgetary restrictions, many small companies fail to implement a testing process. This can, and frequently does, lead to bugs being missed. In this event, the subsequent cost for fixes is invariably higher. The reputational cost is significantly higher though, which can be very damaging. It is not only small companies that must be aware of this factor; larger, more established organisations need to maintain the trust placed in them by delivering quality output.
What can happen if there is no testing?
There is a lack of quality assurance before reaching the customer, potentially tainting the user experience. Security levels can be unchecked, a particular issue in products requiring customers to enter their data. Compatibility issues will go unnoticed ahead of launch, meaning certain devices or platforms may deliver a poor customer journey.
The software testing process
The best way to approach your software testing is to start with planning. Execution is of course a vital element, but if your preparation is poor, this will suffer greatly. It is then important to have clear and concise reporting which summarises any issues or flaws found.
You must know exactly what you are testing, who will be doing it, and which type of testing is required. Read about different types of testing on our Solutions page. You must also understand the requirements of the product to ensure that the expected performance is met. So there you have it, software testing basics; need to know more? Then…
