For system administrators and PC builders, Sandra covers all the bases; it's not quite so friendly towards the general PC user though. Sandra is only available for Windows, but the 'Lite' version is free and comes with a wealth of tests. If you're looking for a more general benchmark that tests your Windows PC in a variety of common situations office applications, video streaming, gaming, etc , then check out PCMark Originally made by Futuremark, in Finland later acquired by UL , the program has been around in various revisions since PCMark monitors various things during the test, such as CPU load and temperature, and the results can be uploaded to UL's database, for comparison with other systems.
There is a separate version of PCMark for Android devices. Another UL benchmark tool and one that's even more popular, 3DMark appeared nearly 22 years ago and has been one of the standard ways of testing graphics cards -- although games have taken over this role, for the most part.
This is because it focuses on running intensive 3D graphics loads, using the latest rendering technology supported by modern graphics cards. There are separate versions for Windows, Android, and iOS, and it comes in a free 'Basic' version that has 4 standard tests.
Next up is another classic benchmark -- the Cinebench tool is actually a very cut down version of a rendering program called Cinema 4D , by Maxon. When you run it, the app uses the CPU to produce a single image, but all done with the latest ray tracing techniques.
The GPU isn't used in the test, other than to send the output to the monitor, but it's great for analyzing how well a CPU manages threads and memory. Cinebench can be configured to render the scene using a set amount of threads, starting with just 1 essentially just one core of the CPU and then all the way up to Even if the processor doesn't support that many threads, the benchmark will still run, as each string of instructions processes a small area of the image - in other words, using more threads just means each rendered section is smaller.
You'll find Cinebench results in just about every CPU review on the web, but be aware that the older versions don't run the same test, so the results aren't comparable. While it's not a detailed workout for your whole system, there's nothing better than watching your new multicore processor rip through the scene. It's totally free, and available for Windows and macOS.
Another popular CPU benchmark that is based on rendering tasks is Corona. This application is based on the Corona Renderer and lets you compare the performance of your CPU against a big results database. Basemark might seem to be a bit of a 3DMark clone and part of the development team are ex-Futuremark employees but this graphics test has an important advantage over its Finnish rival: there are versions for Windows, Linux, MacOS, Android, and iOS.
So if you're a professional hardware tester or you just have lots of gear to check out, Basemark GPU might just suit your needs. For a single rendering test, it's quite a large download at just under 1 GB; and if you want to explore how well your graphics card handles different types of texture compression, there's even more to pull down from their servers.
There's a free version for all platforms, but if you want to unlock the ability to automate the test or configure them outside of what Basemark have set, then you're probably out of luck.
That's because those features are only available in the Corporate edition and there's no public price tag for that! If you're into overclocking or you've just built a new system and you want to test how stable it is, then you'll want a program to stress test your computer. OCCT Overclock Checking Tool fits the bill very nicely, and although it's only for Windows machines, it can monitor a variety of sensors and hardware levels as it's running.
Blender is an open source software for 3D modeling, rendering, animation and post-production. The benchmark is based on this software and was developed by the project's team to collect hardware test results and make comparisons between system hardware, installations, and to assist developers to track performance during Blender development.
The benchmark can be run online or offline. The benchmark runs Blender and renders production files, with the option to upload your results to the Open Data portal on blender. Another popular benchmarking tool is Geekbench, by Primate Labs. This is has also been around for a long time, but in the past, it's also had its fair share of negative criticism, notably by key industry figure Linus Torvalds.
The interface is as basic as they come, and there are no fancy graphics while it's running. Instead, it quietly runs a series of tests, performing calculations as used in various computational workloads, and displays the results in the form of list of scores.
Like many benchmark tools, the results can be uploaded to the maker's online database, which means you can compare your findings against other systems or share your own. Geekbench comes as a free, unlimited 'trial' version, that does everything you need it to. If you're after another multi-platform tester, then you should consider giving Novabench a look.
While it lacks the graphical fidelity of the likes of 3DMark or the range of analytical tests that Sandra offers, the whole benchmark is short and sweet it's much quicker than Sandra, for example and there's an online comparison feature, too. What if you want to benchmark your computer Windows, Linux, or macOS-based , but you don't want to pay out for the full set of features? Or let's say you're a IT professional and you need to remotely test and monitor hardware, what then?
Well, it's simple: open-sourced Phoronix Test Suite is what you need. A word of caution is needed though: Phoronix is not for the general, or even enthusiast, consumer. You need to be very comfortable with using a command-line interface, and understand what's being tested, and how each benchmark works.
But if you are a network manager or a system developer, then you won't find a better collection of benchmarking tools anywhere else. The default download comes with a vast number of tests, but additional ones can be sourced through the supporting OpenBenchmarking website. Just go to 'Tools', click on 'Benchmark', and away you go. Clearly this isn't a benchmarking tool, but it's nearly always shown in CPU reviews because it presents a real-world testing scenario.
The compression test is good at seeing how capable the cache of the CPU and the system memory are, in terms of bandwidth and latency; the decompression results are more affected by the CPU's internal structure and how well it manages random, branching integer operations.
So if you're looking to compare these aspects across different makes and models of processors, 7-zip is handy to use and like Cinebench , it's results are often shown in CPU reviews. The best part of the program is that there is no cost, and it's available for Windows and Linux users.
The next entry in our benchmarking list is actually a collection of programs, all made by Unigine , who have been developing 3D graphics engines for gaming and visualization industries for 15 years. The average enterprise application has 50 external dependencies. Eggplant enables robust end-to-end testing for your entire tech stack. There are over 50 different types of system testing. The specific types used by a tester depend on several variables.
Those variables include:. Skip to content. What is System Testing? Report a Bug. Previous Prev. Next Continue. Home Testing Expand child menu Expand. Just like the development world has many concepts and methodologies for creating software, there are many ways to think about how to test and the field is changing all the time.
Early in my career, it could be perceived as a slight or insult to call someone who worked in testing a tester; they preferred to be called QA or quality assurance professionals. Just a year or two ago, I attended a testing conference and I made the mistake of calling someone a QA person. They corrected me and said that tester was the preferred term. When you do black-box testing, you are only concerned with inputs and outputs. Most testing is done in this fashion because it is largely unbiased.
Real white-box testing is when you understand some of the internals of the system and perhaps have access to the actual source code , which you use to inform your testing and what you target.
With white-box testing , you have at least some idea of what is going on inside the software. Oftentimes, unit testing is called white-box testing, but I disagree.
Unit testing is not testing at all. Advantages Disadvantages Discovering of hidden bugs more efficiently Tester needs to have coding knowledge Code will be optimized Code access required Fast problem and bug spotting Focus on existing software, missing functionality may not be discovered. The basic idea of acceptance testing is that you have some tests which test the actual requirements or expectations of the customer, and other tests that run against the system as a whole.
This kind of testing could be testing the functionality of the system or it could be testing the usability or both. Automated testing is any testing in which the execution of the test and the verification of the results is automated.
So, you might automate the testing of a web application by running scripts which open up a web page, input some data, push some buttons and then check for some results on a page.
You could also automate the testing of an API by writing scripts which call out to the API with various data and then check the results that are returned. More and more of testing is moving towards automated testing because manually running through test cases over and over again can be tedious, error-prone and costly—especially in an Agile environment where the same set of tests may need to be run every two weeks or so to verify nothing has broken.
This brings us to regression testing, which is basically testing done to verify that the system still works the way it did before. This is extremely important with Agile development methodologies where software is developed incrementally and there is a constant potential that adding new features could break existing ones.
In fact, you could really make the argument that all automated tests are regression tests since the whole purpose of automating a test is so that it can be run multiple times. Functional testing is another broad term used in the testing world to refer to testing activities where what is being tested is the actual functionality of the system.
So, functional testing is the kind of testing where you are really concerned with the system doing what it is supposed to do from a functional perspective. But, there is definitely some legitimacy to the idea of exploratory testing and perhaps I am a bit too harsh and judgmental.
The idea behind exploratory testing—when done correctly—is that you have some guidelines and a basic plan of which application areas you are going to test and ways you are going to test them. Then, you go about without actual test cases and explore the application, looking for things that might be wrong or behavior that is unexpected. Oftentimes, exploratory testing sessions are recorded, so that if an error is found, the problem can be reproduced by retracing the steps taken by the exploratory tester.
Different organizations are going to have very different ideas of how testing should be done and what process should be followed. So, again, like a large amount of what I said about testing, the idea here is not to be prescriptive or to perfectly model the perfect testing process, but rather to give you an idea of what the testing process is like in general and what it entails. These are all questions that are generally answered in the test plan, or if the test plan is not a formal document, the test planning for a project.
Next, the tests are usually designed at a high level based on the requirements or functionality of the system. At this stage, a tester might be coming up with a list of general test cases which will be run, what kinds of conditions will be tested, and coming up with what will be needed to perform the tests.
