Software Testing

Software testing is needed whenever new software products are in developement. Testers are needed to be able to find bugs and errors, before the final product is ready to be realesed. Sometimes companies will higher people to just test their latest products, and try everything out to find bugs ect.

A solid product must be bug free, so software testing is the a very essential part of completing a product.

About automated software testing

What is automated software testing?
The automated testing software procedure can be a very time saving task.
A proper Software has to be tested in order to confirm that all valid inputs are correctly interpreted and executed, while incorrect user or server inputs are thrown out. Automated Software tests also verify that results are generated efficiently, and that a large volume of data can be handled without hiccups. Automated Software Testing can be carried out either manually or electronically. Automated software testing involves the use of specialized software to test the code that is under development. Such automated Software testing benefits greatly the software development procedure, when applied intelligently.
Many manual tests depend on the strictness of the people doing the testing. Manual software testing in contrary with Automated Software testing, is time-consuming, and needs a significant ratio of testers to developers for most applications. This raises the cost of development. In addition, manual testing opposed to Automated Software testing has the limitation that large amounts of data, or large numbers of simultaneous users or inputs, cannot be tested easily and effectively without losing lots of time and money.
Many programming organizations and groups are relying heavily on automated software testing, especially organizations that use test-driven development. There are many frameworks to write tests in, and continuous integration software will run tests automatically every time code is checked into a version control system.
What are the benefits of automated software testing ?
Firstly we have to know that, the automated testing software cannot go beyond this on its own because it's nothing more than a procedure, which needs a human hand to take hold of its arms and guide it through.
While software automation cannot reproduce everything that a human can do (and all the ways they think of doing it), it can be very useful for regression testing. However, it does require a well-developed test suite of testing scripts in order to be truly useful.
Automated software testing programmatically controls test execution, and the evaluation of output. The testing software provides inputs, which correspond to different software user-written conditions, to the software that is being currently evaluated. For each set of conditions, the testing software compares the actual results to requested results, and maintains statistics on the total behavior of the target software. Following a “run”, the automated testing software procedure typically provides summary results so that people can rapidly determine what to remedy.
The automation testing software has to be provided the longing inputs and outputs. One way to do this is to save manual test conditions into the software. Another way is to write code to generate various conditions, within the acceptable limits of the software to be tested. Thus, the basis of automated software testing certainly requires human effort.

Introduction to Software Testing 
The classification of Software Development Life Cycle process is as follows
Software Development
Software Testing
Software Testing is an important factor in a product's life cycle, as the product will have greater life, only when it works correctly and efficiently according to the customer's requirements.

Before moving further into the introduction to software testing, we have to know a few concepts that will simplify the specification of software testing.

Some Software Testing definitions
Software Testing term: Error: Error or mistake is a human action that produces wrong or incorrect result.
Software Testing term: Defect (Bug, Fault): A flaw in the system or a product that can cause the component to fail or misfunction.
Software Testing term: Failure: It is the variance between the actual and expected result.
Software Testing term: Risk: Risk is a factor that could result in negativity or a chance of loss or damage.

So, Software testing is the process of finding defective lines in code or buggy functions in the system, that occurs due to an error in the application, which could lead to failure of an ongoing product and increase in probability of high risk. In short, software testing have different goals and objectives, which often include:

Objectives of Software Testing
finding faults in an application.
gaining confidence in and providing information about the level of quality.
preventing faults in an application.

Helping the beginners of Software Testing
Getting into the Scope of Software Testing

The primary execution of software testing is to detect bugs in order to correct and uncover them. The logic of software testing includes execution of that code in various environment and also to examine the aspects of code - check whether the software does what it is supposed to do and works according to the specifications? As we move further we come across some questions such as "When to start testing?" and "When to stop testing?" It is recommended to start testing from the initial stages of the software development. This not only helps in regulating unusual errors before the last stage, but also reduces the rework of finding the bugs in the initial stages every now and then. It also saves the cost of the defect required to find it. Software testing is an ongoing process, which is potentially endless but has to be stopped somewhere, due to the lack of time and budget. It is required to achieve maximum profit with good quality product, within the limitations of time and money. The tester has to follow some procedural way through which he can judge if he covered all the points required for testing or missed out any. To help testers to carry out these day-to-day activities, a baseline has to be set, which is done in the form of checklists. Read more on checklists for software tester.

Software Testing Key Ideas
Faults and Failures: As we discussed earlier, defects are not caused only due to the coding errors, but most commonly due to the requirement gaps in the non-functional requirement, such as usability, testability, scalability, maintainability, performance and security. A failure is caused due to the abnormality between an actual and an expected result. Some imperfections of the software can often result to failures. A defect can turn into a failure due to the change in the environment and or the change in the configuration of the system requirements.
Input Combination and Preconditions: Testing all combination of inputs and initial state (preconditions), is not feasible. This means finding large number of infrequent defects is difficult.
Static and Dynamic Analysis: Static testing does not require execution of the code for finding defects, whereas in dynamic testing, software code is executed to demonstrate the results of running tests.
Verification and Validation: Software testing is done considering these two factors.
Verification: This verifies whether the product is done according to the specification?
Validation: This checks whether the product meets the customer requirement?
Software Testing Quality Assurance: Software testing is an important part of the software quality assurance. Quality assurance is an activity, which proves the suitability of the product by taking care of the quality of a product and ensuring that the customer requirements are met.
