Manually repeating these tests is costly and time consuming. Once created, automated tests can be run over and over again at no additional cost and they are much faster than manual tests. Automated software testing can reduce the time to run repetitive tests from days to hours. Test Automation software is the best way to increase the effectiveness, efficiency and coverage of your software testing.
Manual testing is the process of manually testing software for defects. It requires a tester to play the role of an end user whereby they use most of the application’s features to ensure correct behavior. To guarantee completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases.
A key step in the process is testing the software for correct behavior prior to release to end users.
For small scale engineering efforts (including prototypes), exploratory testing may be sufficient. With this informal approach, the tester does not follow any rigorous testing procedure, but rather explores the user interface of the application using as many of its features as possible, using information gained in prior tests to intuitively derive additional tests. The success of exploratory manual testing relies heavily on the domain expertise of the tester, because a lack of knowledge will lead to incompleteness in testing. One of the key advantages of an informal approach is to gain an intuitive insight to how it feels to use the application.
Large scale engineering projects that rely on manual software testing follow a more rigorous methodology in order to maximize the number of defects that can be found. A systematic approach focuses on predetermined test cases and generally involves the following steps.
Choose a high level test plan where a general methodology is chosen, and resources such as people, computers, and software licenses are identified and acquired.
Write detailed test cases, identifying clear and concise steps to be taken by the tester, with expected outcomes.
Assign the test cases to testers, who manually follow the steps and record the results.
Author a test report, detailing the findings of the testers. The report is used by managers to determine whether the software can be released, and if not, it is used by engineers to identify and correct the problems.
A rigorous test case based approach is often traditional for large software engineering projects that follow a Waterfall model. However, at least one recent study did not show a dramatic difference in defect detection efficiency between exploratory testing and test case based testing.
Testing can be through black-, white- or grey-box testing. In white-box testing the tester is concerned with the execution of the statements through the source code. In black-box testing the software is run to check for the defects and is less concerned with how the processing of the input is done. Black-box testers do not have access to the source code. Grey-box testing is concerned with running the software while having an understanding of the source code and algorithms.
Static and dynamic testing approach may also be used. Dynamic testing involves running the software. Static testing includes verifying requirements, syntax of code and any other activities that do not include actually running the code of the program.
Testing can be further divided into functional and non-functional testing. In functional testing the tester would check the calculations, any link on the page, or any other field which on given input, output may be expected. Non-functional testing includes testing performance, compatibility and fitness of the system under test, its security and usability among other things.
Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects), and verifying that the software product is fit for use.
Software testing involves the execution of a software component or system component to evaluate one or more properties of interest. In general, these properties indicate the extent to which the component or system under test.
As the number of possible tests for even simple software components is practically infinite, all software testing uses some strategy to select tests that are feasible for the available time and resources. As a result, software testing typically (but not exclusively) attempts to execute a program or application with the intent of finding software bugs (errors or other defects). The job of testing is an iterative process as when one bug is fixed, it can illuminate other, deeper bugs, or can even create new ones.
Software testing can provide objective, independent information about the quality of software and risk of its failure to users or sponsors.
Software testing can be conducted as soon as executable software (even if partially complete) exists. The overall approach to software development often determines when and how testing is conducted. For example, in a phased process, most testing occurs after system requirements have been defined and then implemented in testable programs. In contrast, under an agile approach, requirements, programming, and testing are often done concurrently.
The outline we propose is not universal. Actually, every single project requires a tailored approach that suits it best. We tried to present the example of an efficient QA process for you to know what to expect from your potential QA consultant.
We serve companies that:
Sometimes, your team understands the problem (many defects missed, stably high testing cost, faulty dev-QA collaboration, and more), but the attempted recovery measures don’t work. In this case, we:
Our specialists are ready to help you pass process and/or product certification. We offer pre-certification for:
To help you achieve your certifcation goals, we:
ScienceSoft’s specialists follow a comprehensive approach to software quality assurance consulting. The key QA consulting stages are:
ScienceSoft’s consulting specialists explore the situation in full: they study the relevant documents, interview stakeholder subgroups and examine the existing QA procedures.
The consulting team identifies problems, possible solutions, and solution-related risks. Relying on the solution and risk analysis, the team develops an action plan and presents it to the customer.
Upon the customer’s approval, a QA consulting team implements the proposed solutions (or a part of them), supervises the process, prevents possible issues and addresses actual ones (if any). ScienceSoft’s QA consultants ensure knowledge transfer to the customer’s QA team.
ScienceSoft’s QA consultants supervise your team performance for some time, ready to step in and address possible problems.

Expertise in QA backed by professional domain knowledge in the following fields:
Performance metrics are essential to either eliminate or remove the variations in the product or process. Using these measures, you can track the progress of your QA team over time and make executive decisions about future projects. Performance metrics allow you and your QA team to continuously learn and improve your processes.
Performance measures relate to how individual projects are progressing. In this process, keep in mind to analyze not only if goals are being met, but also if all the resources are being utilized to their maximum capacity. Performance measures and analysis shouldn’t just involve the executive decision makers, but the entire team. This will help encourage and motivate the QA team to maximize productivity.
There are many other benefits of performance measurements as well including, but not limited to understanding the problems in the process, analyzing the customer expectations and making improvements to current processes.
Below are two examples of metrics that can be measured.
Number of defects found in any given build
This is a way to measure the stability of builds over time. It can also be used to compare various builds. The number of defects found should decrease from one build to the next over the course of the project. However, if a new feature is introduced, this may not be the case. In fact, additional features may actually increase the bug count. Over the course of the project, the number of defects found in each build should steadily decrease till the build becomes stable.
