Following relevant industry blogs and thought leaders via social media, RSS feed or simply by checking their pages regularly is a quick and easy way to keep up with evolving trends and learn new tricks of the trade. As you get started, we recommend taking a look at the following:. Often times the best way to hone these skills is through relevant courses, whether online or in person. We recommend the following:. Coding is quickly becoming one of the most valuable skills to have in the technology world. In general, knowing how to code can open a lot of doors for you career-wise and is simply not a skill you will regret learning.

There are several coding boot camps, academies and online learning communities that can help you becoming a coding master. Some of our favorites include:. Going through the certification process not only boosts your skills and knowledge, but also helps drive career growth. A certification can signal to both potential and current employers and coworkers that you have reached a certain level of experience and have a specific skillset. As Agile methodology remains among the most popular approaches to software development, having an Agile certification can go a long way toward helping elevate and expand your role within projects.

Certifications to consider include those from the Scrum Alliance and the Project Management Institute which include both general project management and Agile specific options as well as those from newcomers ICAgile and Scaled Agile. Conferences also tend to be jam-packed with expert advice, making them an excellent resource for beefing up your skills, learning new things and networking with thought leaders directly. Here our some of our favorite software testing conferences :. Whether you need expert advice, are searching for the right tools for the job or just want to hear about the latest trends in the industry, we have you covered.

I hope software testers review these pointers. I think item 3 practice good test management and reporting is arguably the most important practice. There are so many details you need to monitor in software testing so you need a well-organized system in place and a way to review things easily. The adage measure twice, cut once applies here as you want to ensure your testing system is flawless. Great content on the guidelines to becoming a great software tester.

Metric:A metric is a quantitative measure of the degree to which a system, system component, or process possesses a given attribute. The software quality assurance SQA group is a team of people with the necessary training and skills to ensure that all necessary actions are taken during the development process so that the resulting software conforms to established technical requirements.

Principles Principle 1. Testing is the process of exercising a software component using a selected set of test cases, with the intent of i revealing defects, and ii evaluating quality. Principle 2. When the test objective is to detect defects, then a good test case has a high probability of revealing undetected defect s.

Principle 3. Test results should be inspected meticulously. Principle 4. A test case must contain the expected output or result. Principle 5. Test cases should be developed for both valid and invalid input conditions. Principle 6. The probability of the existence of additional defects in a software component is proportional to the number of defects already detected in that component. Principle 7. Testing should be carried out by a group that is independent of the development group.

Principle 8. Tests must be repeatable and reusable. Principle 9. Testing should be planned. Principle Testing activities should be integrated into the software life cycle.

Testing is a creative and challenging task. A tester needs very good programming experience in order to understand how code is constructed, and to know where and what types of, defects could occur. A testers also need to work with requirements engineers to make sure that requirements are testable, and to plan for system and acceptance test. Testers also need to work with designers to plan for integration and unit test. Testers also need to cooperate with software quality assurance staff and software engineering process group members.

2. Exhaustive testing is impossible

Testers need the support of management. Software engineers work very hard to produce high-quality software with a low number of defects. A tester develops hypotheses about possible defects.

12 Principles of Agile Software Development

Test cases are then designed based on the hypotheses. Defect Repository To increase the effectiveness of their testing and debugging processes, software organizations need to initiate the creation of a defect database, or defect repository. The defect repository supports storage and retrieval of defect data from all projects in a centrally accessible location.

Defects injected in early phases can be very difficult to remove in later phases. Feature defects are due to feature descriptions that are missing, incorrect, incomplete, or unnecessary. Coding defects classes are similar to design defect classes. Some coding defects come from a failure to understand programming language constructs, and miscommunication with the designers.

These defects are called testing defects. Defects in test plans are best detected using review techniques. There is also the option of using a platform that automates a number of functions, including testing.

You should also make it easy for them to offer opinions such as enabling them to make suggestions or report errors right in your app. Testing does add some overhead, but if you do it intelligently, you can experience very little delay in delivery. The process is automated, and it often runs on virtual machines. Ephemeral environments , whereby environments are created quickly and torn down just as fast after finishing a stage, are another option that can help.

As you consider you own smart testing approach, you can use the the following testing pyramid as a guide for the amount of effort needed. Their focus is on covering the end-to-end critical use cases. If you keep these principles in mind, your testing is more likely to be successful. And that success means you're achieving the results you and your users want. Or, there's another option: developing with OutSystems.

Defects Found Later in the Development Cycle Are More Expensive As the following graph illustrates, the cost of fixing a defect grows as the software reaches the production phase, and in the later stages may be more than times higher than in the dev and build stages.
