Characteristics of Reliability testing

Today, we will have a look at Reliabilty testing. We will try to understand the concept covering the various aspects related to it. Testing classes in Pune train students in the software testing domain. To get more details about the same, you can search for software testing courses in Pune.

Let us go ahead with reliability testing.

Reliability Testing is all about execution of an application with the goal that bugs are found and resolved before the system is deployed. The aim of reliability testing is to decide the product reliability, and to check if the software meets the customer’s reliability demands.

Characteristics of Reliability testing:

  • Reliability alludes to the consistency of a measure. A test is viewed as reliable in the event that we get a similar outcome more than once. Software Reliability is the likelihood of failure free software functioning for a predefined time-frame in a predetermined environment. Software Reliability is additionally a critical element influencing system reliability.

  • Reliability testing can be carried out at different levels. Complicated systems can be tested at component, unit, subsystem, system, circuit board and assembly levels.

  • As indicated by ANSI, Software Reliability is defined as: the likelihood of failure free software operation for a predefined time-frame in a predetermined environment. Software Reliability is not an immediate function of time. Electronic and mechanical parts may turn out to be towards becoming “old” and destroy with time and use, however software won’t rust or destroy amid its life cycle. Software won’t change after some time unless purposefully changed or updated.

  • Reliability testing will have a tendency to reveal prior those failures that are in all likelihood in real-time operations, in this manner coordinating endeavors at settling the most imperative shortcomings.

Software reliability plays an important role in software quality. Software reliability can be divided into three parts as below:

  1. Modeling

  2. Measurement

  3. Improvement

  1. Modeling:

Software reliability modeling has developed to the point that significant outcomes can be gotten by applying appropriate models to the issue. There are a number of models that exist, yet no single model can catch an essential measure of the software characteristics. Assumptions and abstractions must be made to simplify the issue. There is no single model that is all inclusive to every one of the circumstances.

  1. Measurement:

Software reliability estimation is naive as of now. Measurement is a long way from commonplace in software, similar to other engineering related fields. “How great is the software product, quantitatively?” As straightforward as the question may be, there is still no clever response. Software reliability cannot be measured directly, so other related aspects are measured to gauge software reliability and compare it with other products. Development process, shortcomings and failures found are all elements identified with software reliability.

  1. Improvement:

Software reliability improvement is difficult. The trouble of the issue originates from deficient comprehension of software reliability and on the whole, the attributes of software. Up to this point there is no great approach to vanquish the complexity problem of the software. Complete testing of a modestly complex software module is infeasible. Free of defects software product can not be guaranteed. Real-time constraints of time and spending plan severely restrains the efforts put into software reliability improvements.

For an organization to perform reliability testing is generally costlier than the typical functional testing as it requires more change and swings to distinguish the application breakpoint and loads of technical abilities and experience on the testing resource side.

The Role of Volume Testing In Software Testing

As a part of our software testing article series, today we will be seeing what is volume testing, and the various aspects related to it.

With proper professional training, you can tap the various opportunities for software testing jobs in Pune. As far as training in software testing is concerned, a software testing course in Pune can be of great help. It would train you in various software testing related modules.

Now, let’s focus our attention on understanding Volume testing.

It comes under the category of non-functional testing. Volume testing is nothing but testing a software application or product with a specific amount of data. E.g. in the event that we need to volume test our application with a particular database size, we have to extend our database to that size and afterwards test the application’s performance based on it.

  • Volume testing” is a term stated and elaborated in The Art of Software Testing, 1979, by Glenford Myer. As per his definition, Volume testing is “Subjecting the program to heavy volumes of data. The purpose of volume testing is to show that the program cannot handle the volume of data specified in its objectives” – p. 113.

  • The role of volume testing is to decide system performance with expanding volumes of data in the database.

  • Test cases are extracted from design documents

  • Data to be tested is normally generated with the help of a test data generator.

  • A small amount of data is tested during the developmental phase.

  • The test data used is just to assess the system performance. Test data is not required to be logically correct.

  • Post the completion of testing, results are logged and tracked to bring it to closure.

  • Software performance deteriorates with time since there is huge amount of data overtime.

Checklist for Volume testing:

  • Checking the response time of the system.

  • Check for any data loss.

  • Check if data is being overwritten sans any notification.

  • Check whether data is being stored in an incorrect manner.

Testing courses in Pune usually help in terms of providing job assistance as well.

Examples of Volume Testing:

In the event that you are planning for a software to be utilized on 1,000 PCs, you ought to reproduce the utilization of the system on a similar number of PCs. That is what you call as volume testing. All the actual exercises that will be performed by the users ought to be reproduced and performed. This will incorporate opening of files, creating documents, and processing data or any utilization the end user will probably utilize the system for.

In the event that you need to test the application with a database of a particular size, the database of the system ought to be extended by adding more data to the system database until it meets the desired objective.

Volume testing vs load testing:

Volume testing makes sure if the software under question functions as per expectations for certain volume of data. Volume can be built by increasing size of the document. As far as load testing is concerned, load tests checks the system performance when the load is increased. Load testing here will be increasing the number of files. Volume testing can be utilized to quantify the throughput while load testing can be utilized for measuring the performance.

Volume-testing services incorporate test management, development of test labs, test strategy designing and planning and test plan development, development of automation testing systems, assistance in making test script, developing test scenarios, test case execution and provide quantifiable test reports.

Hope that you found this article on Volume testing, to be informative. We will come up with more topics related to software testing.

Understanding The Concept Of Compliance Testing

We will be covering the concept of Compliance testing in this particular article on software testing. Software testing training in Pune covers Compliance testing as a part of its course syllabus. To learn this and other concepts related to software testing, opt for the best software testing institute in Pune.

What is it?

It comes under non-functional software testing. It is connected with the IT standards took after by the company and it is the testing carried out to discover the deviations from the organization endorsed standards.

  • Testers ought to take care well while doing this type of testing, are there any downsides in benchmark implementation in our venture and need to do examination to enhance the measures.

  • It makes sure that we are executing and meeting the stated standards.

  • It is nothing but an audit of a system in sync with the known criteria.


Compliance testing is basically a non-functional type of testing technique which is carried out to validate whether the developed software adheres to the company’s defined standards or not.

It is also termed as Conformance testing.

Elaborating Compliance testing:

This is fundamentally a sort of an audit which is carried out on the software to check if all the predetermined standards are met or not. To guarantee that the compliances are met, often a team of regulators and compliance expert individuals are formed in each organization. This board executes a check whether the development teams are meeting the guidelines of the organization or not .The teams carry out an investigation to watch that the measures are legitimately authorized and actualized. The administrative board likewise works at the same time to enhance the measures, which will thus prompt better quality.

Software institutes in Pune offer advanced training in software testing.

When to implement compliance testing?

It is exclusively the management’s call. On the off chance that they need, they need to execute adequate tests to approve the level of compliance to the technique and distinguish the violators. In any case, it might be conceivable that, absence of compliance is because of NOT understanding the concept or they are misconstrued. Management ought to guarantee that the teams have a legitimate and a reasonable comprehension of the guidelines, systems and procedure. They can orchestrate legitimate training for the team if necessary.

It might be conceivable that the standards are not distributed appropriately or might be that the benchmarks itself are of low quality. In such a circumstance, efforts should me made either to correct it or to adopt another approach. It is vital that the compliance check ought to be made right from the origin of the venture than at the later stage since it is hard to redress the application when the necessity itself are not properly archived.

Compliance testing is otherwise called Conformance testing. The measures typically utilized by the IT industry, are fundamentally characterized by the large organizations like IEEE (International institute of electrical and electronics engineers) or W3C (World Wide Web Consortium) and so forth. It can likewise be completed by an independent/third party organization which works in this type of testing and administration.


Compliance testing is performed to guarantee the abiding of the deliverables of each stage of the development life-cycle. These measures ought to be surely understood and archived by the management guys. On the off chance that required trainings and sessions ought to be organized for the team. Compliance testing is fundamentally done through the examination procedure and the result of the review procedure ought to be very much documented.

These were a few facts about compliance testing. Join software testing classes in Pune, to get training in software testing.
