Most definitions of quality whether for a product, service or an application focus on an individual’s (consumer’s) perception related to the specific product, service or application. Quality assurance (QA) services help software developers figure out deficiencies in the current software followed by how best to resolve the issue. That said, not every company is successful in accurately evaluating the software, let alone, suggesting possible means of resolution. Following are key quantifiable aspects of the software, which a company considers, while ascertaining its quality:
Coding Analysis of Application
This is often the first step in comprehensively testing new software. In most cases individual sections of the source code are parsed to separate out objects, control structures, tokens and individual instructions etc. to determine the performance of each section of the source code. The software is then rated on the basis of established standard levels of performance specified for each section of the code. This analysis ensures that critical programming errors are identified as soon as possible and remedial measures are initiated on a priority basis.
Reliability Analysis of Software
Inadequate reliability in case of new software is often caused due to a lack of compliance with good coding as well as architectural practices, while designing the application. By assessing key static attributes, testers can estimate various levels of business risk as well as possibility of defects and failure after the application is put into operation. Some of the key assessment areas to ensure software reliability include transaction complexity level, algorithm complexity analysis, Error and Exception handling across various levels as well as compliance with best practices of structured and object-oriented programming.
Application Security Analysis
Inadequate security in applications can be extremely damaging to a company’s reputation, while often resulting in substantial financial losses. As most such lapses result from poor architectural and coding practices, software testing often focuses on key areas including but not restricted to ensuring that security best practices, code level programming practices analysis, multi-layer design compliance and application architecture practices are adequately followed.
Software Efficiency Analysis
New software requires to be checked for efficiency due to failure on part of developers to follow established best practices of coding and proper architecture. By measurement of known static attributes of the application, Quality Assurance Services can estimate the ability of a program to handle large data volumes, complex algorithm handling, bottlenecks in processing as well as problems of future scalability. By appropriately ensuring that best practices are followed during the development process, efficiency problems of an application may be minimized.
Maintainability of Application
This analysis is determined to ensure that an application is capable of being viable over an extended time period, which ensures maximum ROI. The concept maintainability is directly related to transferability, reusability, testability, changeability, understandability as well as modularity of the software. This type of analysis is not concerned with the code-level analysis instead it focuses on multiple relatively small violations of established best practices in basic programming logic, complexity avoidance strategy and documentation. These small errors tend to produce a major cumulative effect, which adversely affects the overall software quality unless adequate steps are taken to ensure proper maintainability of the application.
Size of the Software
Though size is often not regarded as a key measure of software quality, software size does have some bearing on the user’s perception. To determine the application’s size, the source code is gathered from multiple locations including configuration files, component headers, source code of data manipulation actions as well as all scripts related to the data structure. The most commonly used system is to quantify is determine the total lines of code for every technology, total number of tables, files, functions etc. Alternatively, many software testers follow guidelines of the IFPUG (International Function Point Users Group) by focusing on functional point analysis to measure the functional size of the application for estimating the size. Size-based analysis of software is especially important in QA of mobile only apps that are expected to be the leading revenue generators for the IT industry in 2013 and beyond.
