Making software that your target audience will love is no easy feat; after all, even the most brilliant application won’t do anyone much good unless it is carefully planned, structured intuitively and seamlessly implemented. Here we will look at what an API is, how it is tested and why it matters. What is an API? An Application Programming Interface (API) deals with the core functioning of a program and is made up of a collection of protocols, tools, routines and procedures which together determine how components interact with each other. While API usage first started out as a way to facilitate integrations with a set of closed distributed systems it has evolved considerably over the years and now plays a key role in multi-use integrations with both internal and external systems. How does API testing work? API testing takes place at the business or logic level of the software architecture and validates the complete functioning of a component by conducting a number of targeted tests. Basically, an application is used to send ‘calls’ to the API which triggers various responses and these outputs are then recorded and analyzed to determine reliability, functionality, security and overall performance. Service virtualization is also […]
With software applications becoming more complex and the global number of browsers and devices combinations skyrocketing, comprehensive testing has never been more important; however, a lot depends on your ability to pair the right technique with the right application. The following guide to software testing techniques will hopefully help you acquire a better understanding of this often misunderstood process. Software testing methods The three primary software testing methods are known as Black Box, White Box and Grey Box testing. Here is a brief overview of each one. Black Box With this method, testing is conducted without any knowledge of the software’s source code or system architecture. While this blind approach can be rather inefficient it ensures that testing is conducted from a user-perspective rather than that of the program designer. White Box This method implies that the tester has access to application’s architecture and source code. This enables testers to dig deeper into products and identify issues and their causes more easily. Grey Box A mix of the Black and White Box methods, Grey Box testing is conducted with limited access to the internal workings of the program. For instance, while testers may have access to the architecture and the […]
If you want to ensure that the software you ship is the best possible quality, then you need to maximize your test coverage. The problem is that you have limited time and resources, so how do you maximize your test coverage? Where should you focus your efforts for best results? How can you spread those resources a little further without spreading them too thinly? We have a few tips to share that will hopefully help you maximize that test coverage.
In order to verify that your software works as intended, you’ll obviously need to test it. In order to properly test a specific function or feature, test cases contain a list of actions. For many types of testing, whether it’s manual regression or automation, you need that set of instructions. To create a good test case, there are a few different approaches you might take, but there are certain standards that are worth considering. Today, we’re going to look at a few tips to help you write good, effective test cases. Make it simple and clear. Starting with the naming convention, which should make it easy to understand what the test case is intended to test, you should take your time and ensure that every aspect of the test case is easy to understand. It might need to be followed by a new tester, or form the basis of an automated script later down the line, so clarity is vital. Break everything down into simple, chronological steps so that someone with no knowledge of the project could run the test case. Consider the end user. You might be working from a requirements document, a user story or the application itself. In […]
If you want to get a clear picture of software quality, or find confirmation that a new tool has widened your test coverage, then it may be helpful for you to use test metrics. Only by measuring the right things can you: confirm that the software will meet requirements; identify key areas for testing focus; and find the best processes and tools. Overall, the best way to improve these processes is through test metrics. Here are some of the tools that you can employ to gain useful insights about your current project and your team: Requirements and defects. An important component to look at while testing metrics is requirements coverage. First, check that the software meets the requirements that you originally laid out at the beginning of the project. If not, why not? How many test cases were designed for each requirement? Ensure that someone on your team is tracking what still is in need of design and execution. In addition to requirements, you will want to track defects very closely. Don’t just look at overall defect numbers. Locate where the concentration of defects are and factor in the severity. If areas of the software consistently have a much higher defect rate, a deeper problem may exist. Therefore, encourage testers to log usability issues in […]
