Software testing is the act of examining the artifacts and the behavior of the software under test by validation and verification. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not necessarily limited to:

analyzing the product requirements for completeness and correctness in various contexts like industry perspective, business perspective, feasibility and viability of implementation, usability, performance, security, infrastructure considerations, etc.

reviewing the product architecture and the overall design of the product

working with product developers on improvement in coding techniques, design patterns, tests that can be written as part of code based on various techniques like boundary conditions, etc.

executing a program or application with the intent of examining behavior

reviewing the deployment infrastructure and associated scripts and automation

take part in production activities by using monitoring and observability techniques

Software testing can provide objective, independent information about the quality of software and risk of its failure to users or sponsors.[1]

Software testing can determine the correctness of software under the assumption of some specific hypotheses (see the hierarchy of testing difficulty below), testing cannot identify all the failures within the software.[2] Instead, it furnishes a or that compares the state and behavior of the product against test oracles — principles or mechanisms by which someone might recognize a problem. These oracles may include (but are not limited to) specifications, contracts,[3] comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, applicable laws, or other criteria.

A primary purpose of testing is to detect software failures so that defects may be discovered and corrected. Testing cannot establish that a product functions properly under all conditions, but only that it does not function properly under specific conditions.[4] The scope of software testing may include the examination of code as well as the execution of that code in various environments and conditions as well as examining the aspects of code: does it do what it is supposed to do and do what it needs to do. In the current culture of software development, a testing organization may be separate from the development team. There are various roles for testing team members. Information derived from software testing may be used to correct the process by which software is developed.[5]: 41–43

Every software product has a target audience. For example, the audience for video game software is completely different from banking software. Therefore, when an organization develops or otherwise invests in a software product, it can assess whether the software product will be acceptable to its end users, its target audience, its purchasers, and other stakeholders. Software testing assists in making this assessment.

Faults and failures[edit]

Software faults occur through the following process: A programmer makes an error (mistake), which results in a fault (defect, bug) in the software source code. If this fault is executed, in certain situations the system will produce wrong results, causing a failure.[6]: 31

Not all faults will necessarily result in failures. For example, faults in the dead code will never result in failures. A fault that did not reveal failures may result in a failure when the environment is changed. Examples of these changes in environment include the software being run on a new computer hardware platform, alterations in source data, or interacting with different software.[7] A single fault may result in a wide range of failure symptoms.

Not all software faults are caused by coding errors. One common source of expensive defects is requirement gaps, that is, unrecognized requirements that result in errors of omission by the program designer.[5]: 426 Requirement gaps can often be non-functional requirements such as testability, scalability, maintainability, performance, and security.

Input combinations and preconditions[edit]

A fundamental problem with software testing is that testing under combinations of inputs and preconditions (initial state) is not feasible, even with a simple product.[4]: 17–18 [8] This means that the number of faults in a software product can be very large and defects that occur infrequently are difficult to find in testing and debugging. More significantly, non-functional dimensions of quality (how it is supposed to versus what it is supposed to ) — usability, scalability, performance, compatibility, and reliability — can be highly subjective; something that constitutes sufficient value to one person may be intolerable to another.

4 Types of Software Testing and When You Should Use Them

All software needs to be tested in stages, but which type of testing should you run at which stage? Read this guide to find out.

4 Types of Software Testing and When You Should Use Them

Benjamin Brandall November 14, 2016

Checklists, Coding, Processes, Quality Control, Software, Technology

The way customers see it, your software release cycle looks like this:

Take ages developing the software

Beta test

Add a few features, fix a few bugs

Done!

This isn’t real life. Beta testing is only one type of test your software needs to pass to avoid being a catastrophic failure.

If your software is struggling to get into a usable state, it’s probably because you’re overlooking testing.

Testing is important for two main reasons:

Tests will reveal flaws in your software

Tests will reveal flaws in your software development process

Note: Apart from customer-facing and QA tests, tests are code.

So, keep reading to find the types of software testing you need to make mandatory in your development team, as well as an explanation of how to do it.

Unit testing: the first pitfall

When your vacuum cleaner’s blocked, you detach the pipes to find which section the blockage is in. Every time you detach a pipe, you either rule it out as part of the problem, or discover the issue.

That’s exactly what unit testing is.

A unit can be anything from a full feature to a button, and it’s important you make sure you at least have all the units working individually before you can definitively say the software works as a whole.

Unit testing is essential, and done by the development team, every time when reviewing new parts of the code base.

It can’t be done by non-technical teams because it requires intimate knowledge of the code and is white-box testing (e.g. testing inside the software, not as a user).

See the unit test section of our complete testing process for more information.

Integration testing: check if the units work well together

Integration testing moves one level higher than unit testing, and looks at how the units integrate with each other.

For example, after building a unit for archiving checklists, we might find that it breaks the search function. While integration testing, we’d find out which parts of the code clash and fix that during the debugging phase.

As the video above says, the more units in your software, the more integration test cases that creates as you need to test how everything reacts to everything else.

Integration testing is the next logical step up from unit testing, and one step in the software testing process. It’s at this point that two testing tools come into play: stubs (dummy lines of code written to simulate higher functions) and drivers (functions to call other functions):

Suppose you have three different modules: Login, Home, User. Suppose login module is ready for test, but the two minor modules Home and User, which are called by Login module are not ready yet for testing. At this time, we write a piece of dummy code, which simulates the called methods of Home and User. These dummy pieces of code are the stubs.

On the other hand, Drivers are the ones, which are the “calling” programs. Drivers are used in bottom up testing approach. Drivers are dummy code, which is used when the sub modules are ready but the main module is still not ready.

Taking the same example as above. Suppose this time, the User and Home modules are ready, but the Login module is not ready to test. Now since Home and User return values from Login module, so we write a dummy piece of code, which simulates the Login module. This dummy code is then called Driver. — Rahul Yadav

System testing: does the entire piece of software work as intended?

By the time you get to system testing, you need to have completed both unit and integration tests and have the software fully loaded up in a test environment.

Think of it this way: when you build a computer, you test the power supply, motherboard, etc (unit test). You find the motherboard is getting power from the power supply (integration test), and that the entire computer works as a whole (system test). And so, the system test could be the point where the computer explodes because of some previously unknown reaction between components.

System testing is an extremely broad area and has had entire books written about it, but can be broken down quickly into its main ingredients:

Usability testing: are the user interfaces easy to operate and understand?

Documentation testing: does the system guide explain the features as they work in real life?

Functionality testing: does everything behave as expected and described in documentation?

Inter-operability testing: does the system work with third party systems (different OS, browser, plug-ins, etc.)?

Performance testing: does the system break itself by trying to use too many resources?

Scalability testing: is the system affected by user count, user location, or server load?

Stress testing: what’s the maximum strain the system can take before it breaks?

Load testing: can the system handle the expected strain?

Regression testing: do new features break old ones?

Compliance testing: does the system comply with regulators (e.g. HIPAA)?
