Agile development is a software development approach that breaks the process of developing a large application into smaller parts. Each part, called “iteration”, represents the whole development process and contains planning, design, development, and testing steps. Unlike the Waterfall model, the iterative process adds features one-by-one, providing a working product at the end of each iteration, and increases functionality from cycle to cycle.
What are the benefits of Agile Development?
Since the focus on each iteration is on finding the right solution rather than the complete solution, iterative development ensures that the product is moving in a direction aligned to correct requirements.
Users can provide critical feedback on the entire product rather than just a small sub-system. This helps in improving on the system's design from the very beginning.
Perfect system design is not important at the project's onset since what's not working will anyways be discarded at each iteration.
Stages of Software Development/Software Development Life Cycle
Planning & Requirement Analysis
Requirement Analysis is the most important and necessary stage in SDLC.
The senior members of the team perform it with inputs from all the stakeholders and domain experts or SMEs in the industry.
Planning for the quality assurance requirements and identifications of the risks associated with the projects is also done at this stage.
Business analyst and Project organizer set up a meeting with the client to gather all the data like what the customer wants to build, who will be the end user, what is the objective of the product. Before creating a product, a core understanding or knowledge of the product is very necessary.
Once the required function is done, an analysis is complete with auditing the feasibility of the growth of a product. In case of any ambiguity, a signal is set up for further discussion.
Once the requirement is understood, the SRS (Software Requirement Specification) document is created. The developers should thoroughly follow this document and also should be reviewed by the customer for future reference.
Once the requirement analysis is done, the next stage is to certainly represent and document the software requirements and get them accepted from the project stakeholders.
This is accomplished through "SRS"- Software Requirement Specification document which contains all the product requirements to be constructed and developed during the project life cycle.
Designing the Software
“How will we get what we want?” This phase of the SDLC starts by turning the software specifications into a design plan called the Design Specification. All stakeholders then review this plan and offer feedback and suggestions. It’s crucial to have a plan for collecting and incorporating stakeholder input into this document.
Developing the project
In this phase of SDLC, the actual development begins, and the programming is built. The implementation of design begins concerning writing code. Developers have to follow the coding guidelines described by their management and programming tools like compilers, interpreters, debuggers, etc. are used to develop and implement the code.
After the code is generated, it is tested against the requirements to make sure that the products are solving the needs addressed and gathered during the requirements stage.
During this stage, unit testing, integration testing, system testing, acceptance testing are done.
Once the software is certified, and no bugs or errors are stated, then it is deployed.
Then based on the assessment, the software may be released as it is or with suggested enhancement in the object segment.
After the software is deployed, then its maintenance begins.
Once when the client starts using the developed systems, then the real issues come up and requirements to be solved from time to time.
This procedure where the care is taken for the developed product is known as maintenance.
Our experts work on various SDLC models:
Getting the software is not just the only thing as regular testing of the same is required too! Also, one needs to be assured of it’s quality and hence we also cater to client’s continuous testing (Manual/Automation) & quality assurance.
Automation & Manual Testing
Software testing, essentially comprises of 2 methods –Manual & Automated. There are distinct differences between the testing types. To eradicated human effort is where automation came into existence! Automation Testing is the process of using tools, scripts, and software to perform test cases by repeating pre-defined actions. Test Automation focuses on replacing manual human activity with systems or devices. Because automated testing is done through an automation tool, it consumes less time in exploratory tests and more time in maintaining test scripts while increasing overall test coverage. The benefit of manual testing is that it allows a human mind to draw insights from a test that might otherwise be missed by an automated testing program. Automated testing is most preferable for large projects that require testing the same areas over and over.
The test automation performs testing at three different levels:
Unit Level Automation
Some of the reasons why Automation Testing is important:
Running Tests 24/7: You can start the test from anywhere in the world and anytime you want to. You can even do that remotely if you don’t have a lot of devices or you don’t have the possibility to buy them.
Fewer Human Resources: You just need a test automation engineer to write your scripts to automate your tests, instead of a lot of people doing boring manual tests over and over again.
Reusability: The scripts are reusable and you don’t need new scripts every time. Also, you can redo the steps that are exactly as the previous ones.
Bugs: Automation helps you find bugs in the early stages of software development, reducing expenses and working hours to fix these problems as well.
Reliability: Automated testing is more reliable and way quicker when running boring repetitive standardized tests which cannot be skipped, but may cause errors when manually tested.
Manual Testing is one of the most fundamental testing processes as it can find both visible and hidden defects of the software. The difference between expected output and output, given by the software, is defined as a defect. The developer fixed the defects and handed it to the tester for retesting.
Manual testing is mandatory for every newly developed software before automated testing. This testing requires great efforts and time, but it gives the surety of bug-free software. Manual Testing requires knowledge of manual testing techniques but not of any automated testing tool.
Whenever an application comes into the market, and it is unstable or having a bug or issues or creating a problem while end-users are using it.
If we don't want to face these kinds of problems, we need to perform one round of testing to make the application bug free and stable and deliver a quality product to the client, because if the application is bug free, the end-user will use the application more conveniently. If the test engineer does manual testing, he/she can test the application as an end-user perspective and get more familiar with the product, which helps them to write the correct test cases of the application and give the quick feedback of the application.
Types of Manual Testing
There are various methods used for manual testing. Each technique is used according to its testing criteria. Types of manual testing are given below:
White Box Testing
Black Box Testing
Gray Box Testing
Quality Assurance in Software Testing is defined as a procedure to ensure the quality of software products or services provided to the customers by an organization. Quality assurance focuses on improving the software development process and making it efficient and effective as per the quality standards defined for software products. Quality Assurance is popularly known as QA Testing. It is defined by a cycle famously called PDCA cycle or Deming cycle.
Plan: Organization should plan and establish the process related objectives and determine the processes that are required to deliver a high-Quality end product.
Do: Development and testing of Processes and also “do” changes in the processes.
Check: Monitoring of processes, modify the processes, and check whether it meets the predetermined objectives.
Act: A Quality Assurance tester should implement actions that are necessary to achieve improvements in the processes.
There are various QA tools which help with Quality Assurance. For comprehensive software quality assurance, we will need a different kind of tool which is also known as QA software.
