Software testing curriculum

To ensure that the software works in all intended target systems. Verify thorough testing of every input in the application to check for desired outputs. To obtain customer sign-off so that software can be delivered and payments received. Read more on Levels of Testing. In simple words, what the system actually does is functional testing.

To verify that each function of the software application behaves as specified in the requirement document. Testing all the functionalities by providing appropriate input to verify whether the actual output is matching the expected output or not.

It falls within the scope of black-box testing and the testers need not concern about the source code of the application. In simple words, how well the system performs is non-functionality testing. Non-functional testing refers to various aspects of the software such as performance , load , stress, scalability, security, compatibility, etc.

There are more than types of testing types. Test Artifacts are the deliverables that are given to the stakeholders of a software project. A software project which follows SDLC undergoes the different phases before delivering to the customer. In this process, there will be some deliverables in every phase. Some of the deliverables are provided before the testing phase commences and some are provided during the testing phase and the rest after the testing phase is completed.

Some of the test deliverables are as follows: Free Download Testing Resources. Read more: Detailed explanation — Test Artifacts.

Choosing Software Testing as a career is a good choice. Nowadays companies are more concerned about the quality of their product. No one will release a product without a quality check. You can start your career in Software Testing by learning manual testing concepts first and then move on to automation testing.

There are many good blogs available on the internet to learn Software Testing both theoretically and practically. If you are in the field of Software Testing with good experience in Manual Testing then you can easily shift to Automation Testing by learning any of the popular Automation Testing Tools like Selenium.

Here is a guide on how to move from Manual To Automation Testing. Program Testing is a method of executing a program with the intent of testing program behavior and finding bugs. It shows only if errors are present and cannot show the absence of errors. A good program testing is one that has a high probability of fiding bugs.

And it is also not inferior in coverage than other carefully designed testing techniques. One can also obtain reliability estimate using random testing results based on operational profiles. Effectively combining random testing with other testing techniques may yield more powerful and cost-effective testing strategies.

Not all software systems have specifications on performance explicitly. But every system will have implicit performance requirements. The software should not take infinite time or infinite resource to execute. Performance has always been a great concern and a driving force of computer evolution.

Performance evaluation of a software system usually includes: resource usage, throughput, stimulus-response time and queue lengths detailing the average or maximum number of tasks waiting to be serviced by selected resources. Typical resources that need to be considered include network bandwidth requirements, CPU cycles, disk space, disk access operations, and memory usage [Smith90].

The goal of performance testing can be performance bottleneck identification, performance comparison and evaluation, etc. The typical method of doing performance testing is using a benchmark -- a program, workload or trace designed to be representative of the typical system usage.

Software reliability refers to the probability of failure-free operation of a system. It is related to many aspects of software, including the testing process. Directly estimating software reliability by quantifying its related factors can be difficult. Testing is an effective sampling method to measure software reliability.

Guided by the operational profile, software testing usually black-box testing can be used to obtain failure data, and an estimation model can be further used to analyze the data to estimate the present reliability and predict future reliability.

Therefore, based on the estimation, the developers can decide whether to release the software, and the users can decide whether to adopt and use the software. Risk of using software can also be assessed based on reliability information. There is agreement on the intuitive meaning of dependable software: it does not fail in unexpected or catastrophic ways.

The robustness of a software component is the degree to which it can function correctly in the presence of exceptional inputs or stressful environmental conditions. It only watches for robustness problems such as machine crashes, process hangs or abnormal termination. The oracle is relatively simple, therefore robustness testing can be made more portable and scalable than correctness testing. This research has drawn more and more interests recently, most of which uses commercial operating systems as their target, such as the work in [Koopman97] [Kropp98] [Ghosh98] [Devale99] [Koopman99].

Stress testing, or load testing, is often used to test the whole system rather than the software alone. In such tests the software or system are exercised with or beyond the specified limits.

Typical stress includes resource exhaustion, bursts of activities, and sustained high loads. Software quality, reliability and security are tightly coupled. Flaws in software can be exploited by intruders to open security holes.

With the development of the Internet, software security problems are becoming even more severe. Many critical software applications and services have integrated security measures against malicious attacks. The purpose of security testing of these systems include identifying and removing software flaws that may potentially lead to security violations, and validating the effectiveness of security measures. Simulated security attacks can be performed to find vulnerabilities.

Software testing can be very costly. Automation is a good way to cut down time and cost. Software testing tools and techniques usually suffer from a lack of generic applicability and scalability. The reason is straight-forward. In order to automate the process, we have to have some ways to generate oracles from the specification, and generate test cases to test the target software against the oracles to decide their correctness.

Today we still don't have a full-scale system that has achieved this goal. In general, significant amount of human intervention is still needed in testing. The degree of automation remains at the automated test script level.

The problem is lessened in reliability testing and performance testing. In robustness testing, the simple specification and oracle: doesn't crash, doesn't hang suffices. Similar simple metrics can also be used in stress testing. Testing is potentially endless.

We can not test till all the defects are unearthed and removed -- it is simply impossible. At some point, we have to stop testing and ship the software. The question is when. Realistically, testing is a trade-off between budget, time and quality. It is driven by profit models. The pessimistic, and unfortunately most often used approach is to stop testing whenever some, or any of the allocated resources -- time, budget, or test cases -- are exhausted.

The optimistic stopping rule is to stop testing when either reliability meets the requirement, or the benefit from continuing testing cannot justify the testing cost. Each evaluation requires repeated running of the following cycle: failure data gathering -- modeling -- prediction. This method does not fit well for ultra-dependable systems, however, because the real field failure data will take too long to accumulate. Software testing is more and more considered a problematic method toward better quality.

Using testing to locate and correct software defects can be an endless process. Bugs cannot be completely ruled out. Just as the complexity barrier indicates: chances are testing and fixing problems may not necessarily improve the quality and reliability of the software.

Sometimes fixing a problem may introduce much more severe problems into the system, happened after bug fixes, such as the telephone outage in California and eastern seaboard in The disaster happened after changing 3 lines of code in the signaling system.

In a narrower view, many testing techniques may have flaws. Coverage testing, for example. Is code coverage, branch coverage in testing really related to software quality? There is no definite proof. As early as in [Myers79] , the so-called "human testing" -- including inspections, walkthroughs, reviews -- are suggested as possible alternatives to traditional testing methods. The experimental results in [Basili85] suggests that code reading by stepwise abstraction is at least as effective as on-line functional and structural testing in terms of number and cost of faults observed.

Using formal methods to "prove" the correctness of software is also an attracting research direction. But this method can not surmount the complexity barrier either. For relatively simple software, this method works well. It does not scale well to those complex, full-fledged large software systems, which are more error-prone. In a broader view, we may start to question the utmost purpose of testing. Why do we need more effective testing methods anyway, since finding defects and removing them does not necessarily lead to better quality.

An analogy of the problem is like the car manufacturing process. In the craftsmanship epoch, we make cars and hack away the problems and defects. But such methods were washed away by the tide of pipelined manufacturing and good quality engineering process, which makes the car defect-free in the manufacturing phase.

This indicates that engineering the design process such as clean-room software engineering to make the product have less defects may be more effective than engineering the testing process. Testing is used solely for quality monitoring and management, or, "design for testability".

This is the leap for software from craftsmanship to engineering. There are an abundance of software testing tools exist. The correctness testing tools are often specialized to certain systems and have limited ability and generality.

Robustness and stress testing tools are more likely to be made generic. Mothora [DeMillo91] is an automated mutation testing tool-set developed at Purdue University. Using Mothora, the tester can create and execute test cases, measure test case adequacy, determine input-output correctness, locate and remove faults or bugs, and control and document the test. They are run-time checking and debugging aids. Comments: Relatively clean and fast, but there were issues with the final Grey Box Testing video.

Overall: Worth the time to a cybersecurity person to clear up misunderstandings between similar terms used by developers. This course gives a lot of information about software testing. It shows that testing software is much more than just testing the software. The accent is a bit hard, but it is OK and I understood it.

I like the course and the way it is presented but they should make use of more graphics or pictures to make us understand simply. Forgot Password?
