Security Testing: A Critical Part of Software Testing

Security testing is an important part of software testing and is included in the curriculum of most of the software testing courses in Pune. Look out for a software testing course in Pune with placement. This would help you in getting a job in this field.

Now,

Let’s get into the various aspects related to security testing.

Security testing fundamentally refers to a type of software testing that is done to check whether the application or the software is secured or not. It verifies whether the application is powerless against attacks, in the event that anybody hacks the framework or login to the application with no prior approval or authority.

It basically is a type of non-functional testing.

Security testing characteristics:

  • The six basic parameters that need to be covered under security testing are as follows:

– Integrity- The application and related data is authentic.

– Authentication- Data is genuine or not and the application origin.

– Availability- As the name suggests, this tests the accessibility of the software application i.e. it is dependably up and running, data and administrations are accessible at whatever point required. Likewise, this incorporates the bckup records which are promptly accessible of any disappointment happens.

– Confidentiality- Data or information is protected from theft.

– Authorization- Certain users should have access to authorized functions only.

– Non-repudiation- Assurance that the receiver and sender of information can’t deny the fact of having sent or received the data.

  • It is a process to discover that a information framework protects information and keeps up functionality as proposed.

  • Software security is about making software carry on in the sight of a malicious attack.

  • The security testing is carried out to check whether there is any data spillage in the sense by encrypting the application or utilizing extensive variety of softwares and hardwares and firewall and so forth.

Security testing is a huge subject. Each technology that you utilize, regardless of whether it’s a programming language like .NET or PHP or an element like input validation or authentication, presents another arrangement of security vulnerabilities. Today, we are occupied with giving you a fundamental idea of what security testing is and how it is performed.

Security testing must begin at an early stage to limit defects and cost of quality. It is a decent practice to begin security testing at the time of prerequisite assembling, this guarantees quality of the finished product will be high.

There is no standard approach to test the security of an application, it absolutely relies upon the reason it serves and what are the security hazards present in it. Each time begin security testing by testing the UIs, this is the primary spot of entry for hackers and unlawful users. At that point think what a hacker would likely do in the event that he gets the access or entry into the system, regardless of whether he will steal the credit card data or get access to some personal files and so forth begin some destructive testing i.e. to test what application or system can’t do and after that focus on the error messages you get. When you are finished with every one of these sorts of testing, attempt and burrow further and see what could be the escape clauses with regards to security at the coding level. With some experience, you will have the capacity to perform security testing in a better manner.

Security testing happens to be an important part of software testing and cannot be ignored at any cost. Testing classes in Pune can give you a detailed insight into security testing.

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.

Advantages:

  • 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.

Disadvantages:

  • 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.

Significance:

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.

Concept Of Alpha Testing

Today, we are going to study about alpha testing in this article. It is a very important phase in the software testing process. A software testing course can help you prepare for a career in this field.

If you are based in Pune, a software institute in Pune will offer you various testing related courses.

Now,

Let’s come back to discussing alpha testing.

Alpha testing is amongst the most widely practiced software testing strategy utilized as a part of software development. Its especially utilized by the product development companies.

Alpha testing can be termed as a kind of acceptance testing; performed to distinguish every single conceivable issue/bugs before releasing the software product to end users or public. The main of this testing is to recreate genuine users by utilizing blackbox and whitebox techniques. The point is to execute all the tasks that a run of the mill user may perform. Alpha testing is done in a lab scenario and generally the testers are in house representatives of the company. To put it as straightforward as could be possible, this sort of testing is called alpha simply because it is done at an early time, close to the end of the development of the product, and prior to beta testing.

Some characteristics of Alpha testing:

  • Alpha testing is simulated or real time environment testing by potential clients/end users or an independent test team at the developers’ site. Alpha testing is regularly utilized for off-the-rack software as a type of internal acceptance testing, before the software product goes to the beta testing phase.

  • Alpha testing is nothing but testing of an application when the development phase is going to end. Small design related changes can even now be executed on account of alpha testing.

  • Alpha testing is normally carried out by a team that is not a part of the design team, yet at the same time, within the organization, e.g. in-house software testing engineers, or software QA engineers.

  • This test is conducted at the developers location. Developers keep an eye on the users and note down the issues observed by them.

  • Alpha testing is the final round of testing before the product is released to the end user. It has two stages:

    • In the first phase of alpha testing, the software product is tested by the in-house team of developers. They utilize either debugger software, or hardware based debuggers. The objective is to discover the bugs really fast.

    • In the second phase of the alpha testing process, the product is given over to the software QA team, for additional testing in an environment that is identical to the proposed use.

  • Alpha testing makes use of both the black box and white box testing techniques.

  • Security testing and reliability testing are not a part of the in-depth alpha testing.

  • A lengthy execution cycle can be required in case of alpha testing.

  • Critical bugs or fixes can be tended to by developers promptly in Alpha testing.

Advantages of alpha testing:

  • Clear perspective of the reliability pf the product is given at an early stage.

  • It helps in reproducing the real time user conduct and his environment.

  • It helps in recognizing genuine threats or bugs and permits quick action towards their resolution.

Disadvantages of alpha testing:

It is not possible to test the software with in depth functionality being covered, as it still lies in the development phase.

That was regarding alpha testing and the various aspects related to it. Doing a software course is what is recommended, if you want to enter the field of software development or software testing.
