Software Testing: Understanding Structural Testing

Structural testing is very much a part of software testing. In this article, we will be seeing the concept of structural testing. We will thus come to know as to what is testing of software structure/architecture. What is the need of it? Etc…A software testing course in Pune with placement, will help you to get a software testing job in Pune.

Moving on with structural testing; structural testing is the testing of the structure of the software system or the individual component. Testing is frequently alluded to as ‘white box’ or ‘glass box’ or ‘clear-box testing’ on the grounds that in this kind of testing we are keen on what is going on ‘inside the application/system’.

Highlights of structural testing:

  • In case of structural testing, the testers are needed to have the information of the inside application of the code. Over here, the testers are needed to have the knowledge of how the software is executed, how it functions.

  • Structural testing can be implemented at all levels of testing. Developers utilize structural testing in case of module testing and module integration testing, particularly where there is great tool support in terms of code coverage. Structural testing is additionally utilized as a part of system and acceptance testing, yet the structures are distinctive. For instance, the scope of menu options or real business exchanges could be the structural component in the system or acceptance testing.

  • Amid structural testing the tester is focusing on how the product does it. For instance, a structural technique needs to know how the loops in the software product are functioning. Distinctive test cases might be inferred to execute the loop one time, two times and many times. This might be done paying little heed to the functionality of the software product or application.

Techniques of structural testing:

  • Path coverage:

This technique is concerned with testing all feasible paths which implies, each statement and branch is covered.

  • Branch coverage:

This technique involves execution of a battery of tests to make sure that all branches are tested at least once.

  • Statement coverage:

The aim here is to cover all the programming statements with minimum number of tests.

Structural testing is more dedicated towards how the system does it as opposed to the functionality of the system. It gives more coverage to the testing. E.g. to test a particular error message in an application, we have to test the trigger condition behind it, however, there must be many triggers behind its occurrence. It is conceivable to miss out a great opportunity one while testing the requirements drafted in SRS. Be that as it may, utilizing this testing, the trigger is well on the way to be covered since structural testing means to cover every one of the nodes and paths in the structure of the code.


  • Implementation reasoning needs to be careful on the part of the test developer.

  • Helps extract errors from within the “hidden” code.

  • Helps in pointing out dead code or other such problems keeping in mind the best programming practices.


  • Chances of overseeing a few lines of code by accident.

  • Proves to be costly both because of the time required and the amount of money spent in order to perform white box testing.

  • As white box testing is involved, having detailed knowledge of the programming language is absolutely necessary.

These were a few things about structural testing, which we saw above. Software testing training in Pune can help you to begin a career in this very field.

Maintainability Testing and It’s Significance!

Maintainability testing even though sidelined in majority of the cases, or given lesser priority as compared to other kinds of testing, holds quite a lot of significance in the entire testing process.

In order to work as a testing professional and get a software testing job in Pune, take the help of a software testing institute in Pune.

For now, lets get to understanding the concept of Maintainability testing at the basic level. This will give you a general idea of the concept.

Maintainability testing is the parameter to show how easy is it, to maintain the system. This implies how easy is to analyze, alter and test the application or the product under consideration.

Maintainability testing is the capacity of the product/system to promptly experience any sorts of changes, to upgrade it, keeping in mind the end goal to meet the prerequisites. It is the level of measuring the software or system potential to experience changes, to meet the requirements. These prerequisites may incorporate

  • Resolving defects or errors.

  • Extra functionality.

  • Adjusting to the changing environment.

  • Prevention of unexpected failures,

  • Maintenance in the future and so forth.

Get to learn more about this type of testing with the help of testing classes in Pune.

Maintainability testing would make use of a model of the maintainability necessities of the product/system. The maintainability testing might be determined as far as the efforts required to impact a change under each of the accompanying four classes:

  1. Corrective maintenance:

Correcting issues. The maintainability of a system can be measured as far as the time taken to analyze and fix problems recognized inside that system.

  1. Perfective maintenance:

Upgrading. The maintainability of a framework can likewise be measured as far as the efforts taken to make the required upgrades to that system. This can be tested by noting the time taken to accomplish another bit of identifiable functionality, e.g. a change to the database, and so on. Various comparative tests ought to be run and an average time computed. The result will be that it is conceivable to give an average effort required to actualize determined functionality. This can be analyzed against a target effort and an evaluation made in the matter of whether requirements are met.

  1. Adaptive maintenance:

Adjusting to the changes in the environment. The maintainability of a software can likewise be measured in terms of the efforts required to create required adaptations to that system. This can be measured in the way portrayed above for perfective maintainability testing.

  1. Preventive maintenance:

Necessary steps to reduce future maintenance costs. This is in reference to the actions taken to reduce maintenance costs that may arise in future.

Maintainability testing characteristics:

  • Ensures software’s efficiency to experience the alteration procedure, in order to meet the oftentimes changing requirements of the customers or the clients.

  • Useful for the future maintenance of the system or software.

  • A kind of non-functional testing that guarantees the competency of the system or software to acknowledge alterations in it.

  • Guarantees acquiescence of maintainability characteristics like Stability, Analyzability, Testability, Changeability, Maintainability consistence.

  • Maintainability testing and maintenance testing are two distinct sorts of testing.


Poor old maintainability, dependably consigned toward the finish of the list of software attributes, regularly disregarded completely in master test plans, and often not in any case perceived as the root cause when we later get chomped by impacts of poor maintainability. You would opine that more consideration would be paid to this part of software quality, wouldn’t you? All things considered, there is proof that maintenance related tasks can represent up to 80 percent of the efforts spent on an application, ranging over its whole life cycle. Actually, one ought to expect that most by far of the software product’s life cycle is spent in the maintenance stage.

Hope that you got a feel of Maintainability Testing after reading this article. Join the best software testing institute in Pune and kick start a career in software testing.

Testing Tools and Their Classification

Today, we will learn about the various software testing tools available, and their classification. Software testing classes in Pune conducted by software testing institute in Pune can help you learn these tools in greater detail.

It is not required to have a one on one relationship between a kind of tool portrayed here and a tool offered by a business tool vendor or an open-source tool. A few tools play out a particular and constrained function (some of the time called a ‘point solution’), however a large number of the business tools offer help for a wide range of functions. For instance a ‘test mangement’ tool may offer help for overseeing testing (progress tracking), configuration administration of testware, incident administration, and requirements analysis and traceability. Correspondingly, another tool may give both coverage estimation and test design support.

There are couple of things that individuals are great at in contrast with the PCs. For instance, when you see your companion in a startling spot, similar to a shopping center, you can instantly perceive their face. This is on account that individuals are great at pattern identification, yet it is difficult to develop a software that can perceive a face. Then again there are things that computers can carry out more rapidly and effectively than individuals can do. For instance, addition of 20 three-digit numbers instantly. This is difficult for the vast majority to do, there are chances that you commit a few errors regardless of the possibility that the numbers are jotted down. A computer does this precisely and rapidly. Consider another case, if individuals are made a request to do the very same work again and again, it will be repetitive and they soon get exhausted and after that begin committing errors.

In this way, the thought is to utilize computers to do things that they are better at. Tool support is extremely helpful for repetitive tasks – the computer doesn’t get exhausted and will have the capacity to precisely repeat what was done before and that too with no slip-ups. Since the tools will be quick, this can make those tasks substantially more productive and more relying.

Taking after are the classifications of various sorts of testing tools as per the test procedure exercises. The “(D)” denoted after the sorts of tools demonstrates that these tools are for the most part utilized by the developers. The different sorts of test tools as indicated by the test process exercises are:

1.Test management tool support:

– Test management tools

– Requirements management tools

-Incident management tools

– Configuration management tools

2. Static testing tool support:

– Review process support tools

– Static analysis tools (D)

– Modelling tools (D)

3. Test specification tool support:

– Test design tools

– Test data preparation tools

4. Test execution and logging tool support:

– Test execution tools

– Test harness/ Unit test framework tools (D)

– Test comparators

– Coverage measurement tools (D)

– Security tools

5. Performance and monitoring tool support:

– Dynamic analysis tools (D)

– Performance testing, Load testing and stress-testing tools

– Monitoring tools

An tool that measures some part of software may have couple of sudden side effects additionally on that software. Like, for instance, a tool that records timings for performance testing requirements to communicate closely with that application keeping in mind the end goal to gauge it. A performance tool will set a start time and a stop time for a given exchange with a specific end goal to quantify the reaction time. However, by taking that measurement, that is putting away the time at those two focuses, could really make the entire task take marginally longer than it would do if the tool was not measuring the reaction time. Obviously, the additional time is little, however it is still there. This impact is known as the ‘probe effect’.
