Why do you place the system under a load when you are testing for errors?

You will need a test program (also called a diagnostic) that exercises the functions that are suspected of making errors. You may also have to run this program under a variety of different environmental conditions (e.g. high temperature, low temperature, higher supply voltages, lower supply voltages) to stress the hardware more and increase the chance of finding intermittent errors.
Such testing can often be quite frustrating, I did it on systems that had to operate on full Military temperature range (-54C to +75C) for over a decade and some problems took more than a month of varying test conditions and rerunning tests over and over (even sometimes writing special diagnostics just for that problem) before the cause of the problem could be isolated.

∙ 6y agoYou would place the system under load to be able to test for problems that only show up under certain circumstances. Here are some possible testing scenarios:
1. If your problem is related to the memory, you would typically have a lot of memory, so it may take a while to show up under normal use. But if you were to use all of the memory during testing, it might cause the PC to crash if there is a bad spot in the memory somewhere.
2. Thermal problems can be hard to locate too. A normal user might not use their computer enough to provoke this, but strenuous testing would find it.
3. With multi-core processors, there could be a problem with one of the cores and you might not find it without placing the PC under a load. There could be a problem on one of the higher numbered cores involving some lesser used instructions. But if you were to hammer every core with every instruction multiple times, you could find it.
4. When you put together a new computer, the parts are usually still under warranty. So what you do is do vigorous testing during this period to see if it will break. If it does, then the parts involved can be returned or exchanged.
5. This is good for gamers too since they demand a lot out of their computers. You don't want your PC to crash during a tournament, so you would test it vigorously in advance. So if you simulate the gaming environment or an even harsher environment, and nothing happens, then it should hold up at a gaming tournament. Athletes often see a doctor before a big race or game, so it makes sense that computers used in gaming should get checked out before tournaments.

Why do you place the system under a load to test for error?
When under a load the errors will be shown faster
How many types of system testing?
Basics of software testingThere are two basics of software testing: blackbox testing and whitebox testing.Black box testing is a testing technique that ignores the internal mechanism of the system and focuses on the output generated against any input and execution of the system. It is also called functional testing.White box testing is a testing technique that takes into account the internal mechanism of a system. It is also called structural testing and glass box testing.Black box testing is often used for validation and white box testing is often used for verification.Types of testingThere are many types of testing likeUnit TestingIntegration TestingFunctional TestingSystem TestingStress TestingPerformance TestingUsability TestingAcceptance TestingRegression TestingBeta TestingUnit testing is the testing of an individual unit or group of related units. It falls under the class of white box testing. It is often done by the programmer to test that the unit he/she has implemented is producing expected output against given input.Integration testing is testing in which a group of components are combined to produce output. Also, the interaction between software and hardware is tested in integration testing if software and hardware components have any relation. It may fall under both white box testing and black box testing.Functional testing is the testing to ensure that the specified functionality required in the systemrequirements works. It falls under the class of black box testing.System testing is the testing to ensure that by putting the software in different environments (e.g., OperatingSystems) it still works. Systemtesting is done with full system implementation and environment. It falls under the class of black box testing.Stress testing is the testing to evaluate how system behaves under unfavorable conditions. Testingis conducted at beyond limits of the specifications. It falls under the class of black box testing.Performance testing is the testing to assess the speed and effectiveness of the system and to make sure it is generating results within a specified time as in performance requirements. It falls under the class of black box testing.Usability testing is performed to the perspective of the client, to evaluate how the GUI is user-friendly? How easily can the client learn? After learning how to use, how proficiently can the client perform? How pleasing is it to use its design? This falls under the class of black box testing.Acceptance testing is often done by the customer to ensure that the delivered product meets the requirements and works as the customer expected. It falls under the class of black box testing.Regression testing is the testing after modification of a system, component, or a group of related units to ensure that the modification is working correctly and is not damaging or imposing other modules to produce unexpected results. It falls under the class of black box testing.Beta testing is the testing which is done by end users, a team outside development, or publicly releasing full pre-version of the product which is known as beta version. The aim of beta testing is to cover unexpected errors. It falls under the class of black box testing.Blackbox TestingWhitebox TestingUnit TestingIntegration TestingFunctional TestingSystem TestingStress TestingPerformance TestingUsability TestingAcceptance TestingRegression TestingBeta Testing
What is a performance testing in software testing?
Performance testing is the testing, which is performed, to ascertain how the components of a system are performing, given a particular situation. Resource usage, scalability and reliability of the product are also validated under this testing. This testing is the subset of performance engineering, which is focused on addressing performance issues in the design and architecture of software product.
Is software testing a technology?
The software can be defined as a series of programs and instructions for a computer system to carry out a specific task or task. a) Software Testing Levels: Unit testing, Integration testing, System testing, and Acceptance Testing.
It is a testing process to obtain confirmation by the client or customer of the application under test that the system meets mutually agreed-upon requirements and often occurs before a client or custo?

What is System Testing Life Cycle?
*It is a type of non-functional testing. *It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results. *It is a form of software testing that is used to determine the stability of a given system. *It put greater emphasis on robustness, availability, and error handling under a heavy load, rather than on what would be considered correct behavior under normal circumstances. *The goals of such tests may be to ensure the software does not crash in conditions of insufficient computational resources
What are the different types of testing technique?
Software testing can be black box testing and while box testing.To get the complete information of it, please visit www.istqbsoftwaretesting.blogspot.comHere you can get free istqb software testing tutorial and software testing study material.
Web based application software testing?
Some or all of the following testing types may be performed depending on your web testing requirements. Web Application Testing Checklist: 1. Functionality Testing 2. Usability testing 3.

What is extreme testing?
Extreme testing is testing done under necessary circumstances. Medical tests for deadly diseases can often be considered to be extreme testing.
When was cosmetic animal testing made illgal in Canada?
I am afraid that animal cosmetic testing isn't banned in Canada yet. They are allowed to use animals in medical testing and cosmetic testing, under strict laws that the cosmetics are under a certain policy.
