How Do I Conduct Software Testing?


Software testing is performed to verify that the complete software package functions according to the expectation as defined by the specifications/ requirements. The critical concern is not only to find out every software bug that exists but to ascertain situations that could negatively affect Customer usability and/or maintainability.

The major goals of Software testing by expert QA Firms are as follows:

* Finding defects and flaws which may get created by the programmer while the software developing process.
* Evaluates the potential of a system and system performance
* Gaining confidence in and deliver information about the quality level.
* To prevent bugs and defects.
* Measure the quality of the software
* To ensure that the end result meets both the user and the business requirements.
* To assure that it meets the SRS (System Requirement Specifications) and the BRS (Business * Requirement Specification).

To gain confidence by providing them a quality product. Software testers are the main enforcers of quality.

Hence, Software testing is the entire process of verifying a system with the purpose of identifying any missing errors, gaps, or requirements versus the actual necessities. Software testing is generally categorized into two kinds- functional testing and non-functional testing.



When to start testing activities?

Testing activities should be started as soon as possible to reduce the time and cost to rework and produce software that is hassle and bug-free so that it can be timely delivered to the valued customer. However, in SDLC (Software Development Life Cycle), testing can begin from the Requirements Gathering phase and continued until the software is fault-free and out there in productions. It also depends on the development model that is being used. For instance, in the Waterfall model, testing begins from the testing phase, however, in the V-model, testing is done parallel to the development phase.


Graphing key indicators to help interpret what occurred during the testing process.

What are the key comparisons to start with:

* Response Time vs. Load (“how does system scale?”)
* End-to-End Business process
* Errors vs. Load (“Is the results valid?”)
* Bandwidth throughput over Load (“system bottleneck?”)
* JVM heap memory/GC
* Server CPU vs Load
* System resources (“how’s the infrastructure function?”)
* Page-level
* DB lock contention, I/O Latency

The significant purpose of software testing is to increase the overall project and product quality, and unquestionably to increase the enterprise quality side by side also.

Conclusion:

Testing allows developers to deliver software that prevents unexpected results, meets expectations, and improves the long-term maintenance of the app. Depending upon the purpose of testing, the appropriate methodologies are applied. Quality improvements help the company to reduce post-release costs of support and service while bringing forth customer goodwill that could transform into greater revenue opportunities.

What is the Scope of Automation Testing or Manual Testing in the Future?

Scope of automation testing in the future E ver since technology is progressing at a speedy pace, the demand for getting projects done quicker has increased more than ever. To get projects done fast, the complete procedures followed during a software life cycle needs to become accelerated as well. In the area of software testing, automation can be implemented to save cost and time but only when used in time-taking projects. When it comes to performing regression testing, large scale testing, automation testing is the way to go. It can be a good choice. There are a number of necessary advantages from test automation like Increases the software quality, lessens manual software testing operations and eradicate redundant testing efforts, create extra systematic repeatable software tests, Minimising repetitive work, and generate more consistent testing outcomes, higher consistency.  Execute more software tests and accomplish better testing coverage in a very limited ...
