Higher-Order Testing

A software error happens when a program fails to perform the function that its end user reasonably expects it to do. Even if you performed an absolutely flawless module test, you couldn't ensure that you detected all software bugs. Then, in order to finish the screening, some further testing is required.

Software development is mostly a process of sharing information about the final program and converting this information from one form to another. As a result, the great majority of software failures can be traced to faults, errors, and "noise" during information transfer and translation.

Function Testing

The practice of attempting to uncover differences between the software and the external specification is known as function testing. An external specification is a detailed description of the software's behavior from the perspective of the end user. To execute a function test, you must first examine the specification in order to generate a collection of test cases.

Remember that the function test's aim is to identify problems and inconsistencies with the specification, not to demonstrate that the software fits its external specification.

System Testing

System testing compares the system or software to its initial aims. Focus on translation mistakes created throughout the process of developing the external specification while looking for differences between the software and its objectives.

This makes the system test a critical procedure, because this point in the development cycle is typically the most mistake prone in terms of the software, the amount of errors produced, and the severity of those faults.

Volume Testing

At least a few volume tests must be performed on each software. Volume testing is used to demonstrate that the software cannot manage the volume of data indicated in its objectives.

Stress Testing

The software is subjected to significant pressures, or stressors, during stress testing.

An example would be assessing a typist: A volume test would assess if the typist could handle a draft of a huge report, while a stress test would check if the typist could type at a rate of 50 words per minute.

Usability Testing

Possible flaws, that even the most rigorous automated testing process would likely miss, can still be found when an end user tests the software in a real-world situation.

Security Testing

The practice of attempting to create test cases that circumvent the program's security checks is known as security testing. By looking for security flaws in current software that provide services comparable to the one you're testing, you can create test cases to see if your software has the same issues.

Web-based applications frequently require a greater level of security testing than other types of apps. This is particularly true for e-commerce sites. Although there is enough technology, security testing must be done periodically to assure safety of the software's users.

Performance Testing

Many software have precise performance or efficiency goals, indicating things like reaction times and throughput rates under specific workload and setup conditions. Test cases must be written in such a way that they demonstrate that the software fails to meet its performance objectives.

Compatibility Testing

Most software that are created are not entirely new; they are frequently substitutes for some outdated system. As a result, applications frequently have specific goals in terms of compatibility with, and conversion methods from, the existing system.

In this process, you strive to induce faults when transferring data from one system to another.

Reliability Testing

All sorts of testing aim to enhance software reliability, but if the software's objectives include explicit assertions about quality, specific reliability tests can be developed.

Today's important software systems have even higher reliability criteria, and modern technology should be able to fulfill these objectives.
