Offshore Software Testing

By: deep raj

Software development is the amalgamation of set of activities which translates the needs of the user into a software product.

Software Development in itself is a big challenge and in the present times the challenge is growing bigger and bigger, simply

because software products are multifaceted, made to perform in multi-platforms environments.

The pressures of increasing complexities and the ever changing environment are mounting constantly. To succeed it is

imperative that quality software is developed and delivered. No company can afford to ‘cut a sorry figure’ or ‘tarnish its

reputation’. It is here that Software testing comes into the picture and undoubtedly

plays a crucial role. To prove a system, software testing is the only way out.

Software testing in simple terms is to establish the worth of the software developed. Software testing is done in context

with the efficiency, compatibility and usability of any software developed. Software testing can be categorized as “static

testing “ which in other terms is reviews, walkthroughs or inspections, and “Dynamic

testing“ which is actually running the software with a given set of cases.

Software Testing Types

(i) Black box testing – is based on requirements and functionality, the outputs are analyzed on the basis of the inputs.

(ii) White box testing - is based internal software and working codes.

(iii) Unit testing – is the testing of individual software components or modules, in depth knowledge of the internal

program design and code is essential for performing this test.

(iv) Incremental integration testing – is a bottom to up approach used for testing the newly added functions of the

application.

(v) Integration testing – is done to verify combined functionality of modules, after integration.

(vi) Functional testing – is done to see if an application conforms to its specifications.

(vii) System testing – done to check the software developed in totality and is based on overall requirements and

specifications. It covers all the parts of the system.

(viii) End-to-end testing – it can also be said to be a “mimicry test”. System testing involves testing of a application in

a situation that mimics real-use, which includes interacting with a database, using network communications, or interacting

with other hardware, applications, or systems if appropriate.

(ix) Regression testing – it is a repeat validation for the modifications in any module or functionality of the

href="http://www.commediait.com">software developed.

(x) Acceptance testing - to confirm if the software developed meets the needs of the customer.

(xi) Load testing – It is a performance test i.e. the system is tested under different load levels.

(xii) Stress testing – done to find out the utmost limit of the System there after the system fails.

(xiii) Usability testing – to check the user friendliness.

(xiv) Alpha testing – is a testing done at the end of software development, it helps in making minor design changes.

(xv) Beta testing –the final test before the software developed is released for commercial use.

Success in software development lies in delivering a quality product and Software testing ensures this.

Software testing can be defined as the process in which the tester aims at checking the software for errors and also, verifying that the functional requirements of a software are met. The system is examined under controlled conditions. The basic orientation is detection of faults within the system.

In this process, a program or an application is executed with the intentions of improving its quality. One strives to find the bugs within the software. As software industry has now grown in both size and complexity, so has its wide area of applications. We see soft wares in banking industry, in gaming industry, in management applications etc. Each has its own target customers and users. Before any software is launched, one must attempt to make an assessment as to its audience, customers, etc. The process of testing aims to aid in this regard.

Verification and Validation
Verification is a thwarting mechanism which helps in detection of all the possible weak points within a software before the process of testing actually begins.

Validation takes place after verification and this is where the concrete testing begins. One aims at finding the defects present in the functional requirements or the software’s specifications.

Software Quality
The quality of any software can be determined by the following yardsticks:

· It must be free of bugs
· It must be delivered on the due date
· It must be complete within the budget initially allotted
· It must meet all the requirements and expectations of the client


Software quality assurance
Software Quality Assurance or SQA, as it is popularly known, is a method by which one aims at monitoring the whole process of software engineering and take measures at appropriate durations for ensuring that the quality of the software is not compromised with. This is approached by use of audits of quality management system by which the system was initially built. A few examples of the quality standards are CMMI (Capability Maturity Model Integration) or ISO 9000.

SQA covers the whole process of development of any software and includes the design, coding, control of the code, reviews of the code, managing the configurations and the release of the final product. It is basically a method to control the processes of software development.

Advantages of SQA
· Improved customer satisfaction
· Reduced cost of development
· Reduced cost of maintenance
· Methodology of SQA
· Validation testing
· Data comparison
· Usability testing

   Software Migration

 

By: RTG marketing

Every software development company focuses on developing quality software. The only way to track the software quality is evaluating it at every stage of its development. It requires some kind of metrics, which is obtained through effective testing methods. Each stage of software testing is effectively monitored for the software QA.

1. Software measurements are used for:

2. Deriving basis for estimates

3. Tracking project progress

4. Determining (relative) complexity

5. Understanding the stage of desired quality

6. Analyzing defects

7. Validating best practices experimentally

Here, some software testing metrics are proposed for black box testing that has real world applications. It discusses:

Importance of software testing measurement

Different techniques/processes for measuring software testing

Metrics for analyzing testing

Methods for measuring/computing the metrics

Advantages of implementing these metrics

These metrics helps in understanding the inadequacies in different software QA stages and finding better correcting practices.

What is measurement and why it is required?

The process of assigning numbers or symbols to attributes of real world entities for describing them according to defined rules is called measurement.

For developing quality software, several characteristics like requirements, time and effort, infrastructural cost, requirement testability, system faults, and improvements for more productive resources should be measured.

Measuring software testing is required:

1. If the available test cases cover all the system’s aspects

2. For tracking problems

3. For quantifying testing

Choose the suitable metrics:

Several metrics can measure software-testing process.

Here, the following types of metrics are identified:

Base metrics:

These raw data are collected in a testing effort and applied in formulae used to derive Calculated Metrics.

The Test Metrics comprise of the Number of

Test Cases Passed, Failed, Under Investigation, Blocked, Re-executed and Test Execution Time.

Calculated metrics:

They convert the Base Metrics data into useful information. Every test efforts must implement the following Calculated Metrics:

% Complete

% Defects Corrected

% Test Coverage

% Rework

% Test Cases Passed & Blocked

% Test Effectiveness & Efficiency

% 1st Run Failures

% Failures

Defect Discovery Rate

Defect Removal Cost

Measurements for Software Testing

The corresponding software testing process in software development measures each step for ensuring quality product delivery.

1. Software Size:

The amount of functionality of an application determines this and is calculated by

Function Point Analysis

Task Complexity Estimation Methodology

2. Requirements review:

Before software development, the Software requirement specifications (SRS) from the client are obtained. It must be:

Complete

Consistent

Correct

Structured

Ranked

Testable

Traceable

Unambiguous

Validate

Verified

The Review Efficiency is a metric that offers insight on the review quality and testing.

Review efficiency=100*Total number of defects found by reviews/Total number of project defects

3. Effectiveness of testing requirements:

It is measured by maintaining Requirement Trace-ability matrix and specification of requirements, which should have:


SRS Objective, purpose

Interfaces

Functional Capabilities

Performance Levels

Data Structures/Elements Safety

Reliability

Security/Privacy

Quality

Constraints & limitations

Next comes the updating of the crucial requirement trace-ability matrix or RTM, which determines the number and types of tests.

While measuring the mapping of test cases, the number and priority of requirement it tests, its execution effort and requirement coverage must be determined.

The Requirement compliance factor (RCF) measures the coverage provided by the test cases to one or set of requirement(s).

Mathematically,

RCFj=∑(Pi*Xi)/(maxXi)*(∑Pi)i=1

Where,

j is a set of requirements and (j=1-m);

Xi=2, if the test case (say Tj) tests requirements Ri completely,

=1, if it tests partially,

=0, if otherwise.
Effectiveness=RCFj/Ej where Ej=Time required for executing a test case

4. Evaluating estimation accuracy

Relative error=(A-E)/A where E is estimate of a value and A is actual value.

For a collection of estimates, the mean RE for n projects is

__ n
RE=1/n∑REi
i=1

For a set of n projects, the mean magnitude of RE (MRE) is

___ n
MRE=1/n∑MREi
i=1

Of a set of n projects, an acceptable level for MRE is less than 0.25.

If K is the number of projects whose mean magnitude of relative error is less than or equal to q,
then the prediction quality pred(q)=K/n

5. Measurement of Efficiency in testing process

In software testing, we must keep tabs on what we had planned and what we have actually achieved for measuring efficiency. Here, the following attributes play major roles: -

Cost: The Cost Variance (CV) factor measures the risk associated with cost.

CV=100*(AC – PC)/PC, AC=Actual Cost, PC=Planned/Budgeted Cost.

Effort: Effort Variance (EV) measures effort.

EV=100*(AE – PE)/PE
(AE=Actual Effort, PE=Planned Effort)

Schedule: Schedule Variance (SV) is important for project scheduling.

SV=100*(AD-PD)/PD where AD=Actual duration and PD=Planned duration.

Cost of quality: It indicates the total effort expended on prevention, appraisal and rework/failure activities versus all project activities.

Prevention Effort=Effort expended on planning, training and defect prevention.
Appraisal Effort=Effort expended on quality control activities.

Failure effort=Effort expended on rework, idle time etc.

COQ=100*(PE + AE + FE)/Total project effort.

Product -

Size variance: It is the degree of variation between estimated and actual sizes.
Size Variance=100*(Actual Software Size–Initial Estimated Software Size)/Initial Estimated Software Size

Defect density: It is the total number of defects in software with respect to its size.

Defect density=Total number of defects detected/software size

Mean Time Between Failures: MTBF is the mean time between two critical system failures or breakdowns.

MTBF=Total time of software system operation/Number of critical software system failures.

Defects: Defects are measured through:

Defect distribution: It indicates the distribution of total project defects.
Defect Distribution=100*Total number of defects attributed to the specific phase/Total number of defects.

Defect removal effectiveness: Adding the number of defects removed during the phase to the number of defects found later approximates this.

Benefits of implementing metrics in software testing:

Improves project planning.

Understanding the desired quality achieved.

Helps in improving the processes followed.

Analyzing the associated risks.

Improving defect removal efficiency.

Software interface testing is just one among the many types of software testing that are used by software engineers for software development. Automated testing is one of the most common software test approaches these days. With this, engineers would not have to perform tests or quality assurance manually.

Nonetheless, automation of software test requires that a prior manual testing procedure should be set up and that this conforms to a formalized testing process. To automate the process, special software is used to control test executions, to ready pre-conditions or requirements for the test, and to compare actual outcomes to predicted results. While automated testing enables developers to save time and energy, manual testing is still needed for more complex tests. One of the testing methods that cannot be entirely automated is interface testing.

Interface testing is one of the most important software tests in assuring the quality of software products. In a nutshell, human beings are able to communicate with hardware through an interface. Interface is actually software that consists of sets of messages, commands, images, and other features that allow communication between a device and a user. Various companies use this type of software testing to make sure that their customers will not encounter any problem when using a particular software product once it is delivered to them. In addition, developers usually want their products to be supported by more than one language thus, their need to understand the interface. In this test, developers come up with changes or revisions and introduce these to a software application by taking note of the feedback from end-users. Usually, each end-user is assigned a specific task. During the course of this test, the program flow is checked and evaluated to determine if it matches the natural strategy of the user in navigating within the application. Moreover, this test determines which application areas are initially and usually accessed and its user-friendliness as well.

A moderator is often tasked to undertake this quality assurance test. Throughout the process, he does not need to communicate anything to the end-user. Rather, he will only be documenting or recording the reaction of the user towards the application. At the session's end, he interviews the end-users and endorses their feedback to the software developer. This way, interface testing improves the software's overall acceptance and the consumer's user experience. Factors like functionality, performance speed, the time needed to use the program, the ease with which the user remembers using the program, user satisfaction, and the rate of user errors are the usual criteria that developers have for a well-designed user interface.

Other software testing types aside from interface testing include component testing, system testing, acceptance testing, and release testing. Component testing requires testing all individual components of software design. System testing, on the other hand, involves testing the functional and non-functional requirements of application systems. Acceptance testing evaluates and compares the system against pre-set requirements. Lastly, release testing is conducted to determine if a new system is compatible to the current technical environment.
