Growing Demand from Performance Testing to Engineering

In the modern era, companies have been investing enormously in building next-gen products and platforms using cutting-edge technologies. Yet, there are the plethora of companies leave the assurance for scalability for quite late in the development cycle or do not follow the testing path enough. This in future lead to disruption in services and later can profoundly impact the customer loyalty, brand image, and ROI (or revenue). If the specific website is undergoing slow or poor performance, customers will have no choice but to explore alternating channels. As a better website experience is like a worthy brand, once gone astray, it becomes tricky to retain the customers. Considering the significance of speed-to-market for the success of the project, businesses need the appropriate processes, tools, and skills for an agile delivery. This is where most advantageous performance engineering and testing comes into the picture and assist your enterprise to think out of the box and stay ahead of the curve.

Why Implementing a robust strategy crucial?

Performance engineering, though, is a wide set of processes, and it is also an art based on years of scrutiny and observation that have led to proven practices. Putting into practice a robust strategy has been a cognizant and strategic decision for all types of enterprises operating across varied businesses. Today, validating and ensuring the responsiveness, speed, and stability of an application is absolutely business critical. The range of facets of Performance Testing has been adopted for the same, confirming that the app does not vacillate under unexpected conditions. Though, there has been a shift in conceptual thinking, where the awareness has shifted more from Performance Testing towards Performance Engineering. It critically refers to the techniques that are being applied in the application development lifecycle, which make sure the non-functional necessities. Some of the key necessities are ensuring usage, throughput, and latency of the memory. These features are required to confirm and to judge that the systems are secure, precise, user-friendly, and scalable over even in the long run. As recommended, it is a significantly demanding practice for Agile and DevOps teams to validate the presentation and efficiency of the applications. The careful application of the ideology of performance engineering makes it possible for businesses to support employees, please customers, and boost returns, all at the same time.

The growing recognition is because of the growing complications with new-age apps and the emerging technologies that are creating these manifold layers. Most of the apps these days engage with multiple third-party vendors and parties to drive innovation as well as growth for the customers. For this reason, it is no more a single action driven growth, it just getting increasingly complicated.

Some of the supplementary benefits are given below:

  • Reduced system & hardware expenses
  • Early detection of bugs and application defects
  • Guaranteed customer satisfaction
  • Enhanced revenue & profits with higher conversions
  • Lesser cost of change related to performance tuning
  • Improved experience & quality from a user’s perspective

Within the Agile process, the methodologies for Performance Engineering can be effectively aligned with the ‘shift-left’ approach. It helps to determine the issues way ahead in the product development process. In this fashion, bottlenecks can be identified and reasons can also be uncovered too. Furthermore, the overall system performance can be optimized in this procedure. The well-thought-out Engineering & Test strategy can enable teams to deal with all sorts of the critical challenges that are being posed by inefficiently performing applications. It aids in benchmarking the app performance and eventually assessing against business critical scenarios for efficient test. The digital sphere has countless aspects that keep challenging the app’s flawless functioning and predictable parameters.

What is TDD (Test-driven development) and its Steps?

TDD has become the most popular over the past few decades. Test-driven development also famous and referred as test-driven design, is a method of implementing software programming that intertwines unit testing, programming & refactoring on the source code. TDD (Test Driven Development) uses a different approach to that used in traditional software development.

Advantages of TDD (Test Driven Development)

Simplification – Writing tests first permits software engineers to mainly consider what they want from the code as well as the functions that it will offer. It also forces expert engineers to only the right code in response to the necessities of the tests they have scripted.

Extensible & Maintainability -Old styles of development were faced with the number of challenges around maintainability as well as extensibility. Because TDD is ingrained into the development procedure at such a granular level, it is guaranteed that every single standalone code can be modified without risking side effects to other pieces of the software.

Improved code quality with Refactoring – Refactoring is a central procedure with TDD. It guarantees that developers are always strengthening their code base which will make sure that the software is modular and updated.

Steps of Test-driven development (TDD)

Test Driven Development Process

TDD has the following different steps:

1. Think and write test cases- In the first step, Developer writes the test case without any piece of code in front of him. This is mundane and time-consuming, but make sure that the developer understands the functionality essential and in accordance with that write the test case. The test case is not biased to showpiece of code works rather test cases are to test the expected functions.

2. Red – Run all tests and check failure of test case- The preceding step that follows is to ensure the correct working and that the new test doesn’t pass by any sort of mistake without any new code. This step also eliminates the possibility that the new test always passes.

3. Green – Writing code: In the next step writing code is done that clears the test. The new code isn’t perfect but is later changed as per the necessities. It’s merely designed to test and doesn’t enclose other functionalities.

4. Green -Run automated tests: If every single test case produced simply passes the test, it implies that the code meets all needed specifications. Hence the next step of the cycle can be Refactor the code to remove duplication and to clean it.

5. Refactor your code- This is exactly the same as removing duplication. A refactoring doesn’t damage any existing functionality and assists to remove duplication between production and test codes. The code is now cleaned as needed.

6. Repeat this cycle-The cycle is repeatable as in the past cases with a new test. The critical requirement is that the size of the steps should be simple and not extended, with around 1 to 10 edits between each test run. If fresh code does not satisfy a new test, the programmer should perform extra debugging. Repeatable integration offers revertible checkpoints.

Implementing Test-driven development can be challenging though because there is always the demand of the right people who have the required skill sets for using distinct unit test frameworks. If you have the expert people, then it is always far better to implement Test-driven development in your projects.

We ensure your development process is uninterrupted by changes that can negatively impact the functionality and solution architecture. Our team addresses such changes as rapidly as possible by promptly modifying the testing routine.

Security Testing “THREATS” and “METHODOLOGIES”

There are varied types of security threats that the application or software is prone through that may cost your business enterprise, if not identified. With the progression in technology attackers bang-up some of the innovative and fresh ways to break into the security mechanisms of a system. Hence, it is vital for the testers to be aware of the several kinds of security threats and determine solutions to tackle them.

Here are some of the most common security threats that the expert testers discover during the security testing process:

Threat 1- SQL Injection

Such security attack happens when the hacker inserts degrading SQL statements into the entry field for execution. The aftereffects of SQL injection is sinful as it leads to leakage of classified info from the server database. It can be easily prevented by thoroughly checking the several input fields like comments, text boxes, etc.

Threat 2-URL manipulation

It is the procedure where hackers make the alteration to the URL query string to access information. Applications that use HTTP GET ways to pass critical info between client and server are normally prone to such sort of attack. As such, the tester must change the parameters to find if the server accepts it.

Threat 3-Privilege elevation

In this kind of attack, the hackers can use his/her existing account to increase the privileges to the top levels than what he/she deserves. If the hacker becomes the success in doing so, he/she will use the benefit for running the code and the system will eventually give in.

Threat 4-Data manipulation

It is a type of security attack which includes hackers gaining access to site or application data and makes the modification to it for their own benefits or to humiliate the owner of the website/ app. The hacker does this by approaching the HTML pages of the site.

Threat 5-Unauthorized data access

This is the well-known security attacks where the hacker gains access to data by unauthorized means which comprises:

  • Make use of data-fetching operations to gain access
  • Gaining access to data by evaluating the other’s access
  • Gaining access to reusable client authentication info by keeping track of the success of others.

Threat 6-Identity spoofing

In Identity spoofing security attack, the hackers use the credentials of a valid user or device in order to attack the network hosts, for data theft and to gain the benefits over access controls. IT- infrastructure as well as network-level mitigation are requisite to prevent such attacks.

Threat 7-Denial of Service

It is a major security risk or attack and the attacker aims at making a network or system resource unavailable to the valid users. When software or applications are prone to such threats, the application or the complete system may end up being unusable.

Threat 8-Cross-site scripting (XSS)

Cross-site scripting (XSS) risk allows attackers to insert client-side script in website pages and manipulate them into clicking the URL. After clicking on the URL is done by the users, the code automatically changes the way the website behaves and gives access to the attacker to steal critical information and other personal data.

Some of the security testing tools available for web applications:

  • BeEF (Browser Exploitation Framework)
  • BFBTester – Brute Force Binary Tester
  • Brakeman
  • Vega
  • Google Nogotofail
  • CROSS (Codenomicon Robust Open Source Software) program
  • Ettercap
  • Flawfinder
  • Gendarme
  • Knock Subdomain Scan
  • ZED Attack Proxy (ZAP), etc.

Security Testing: Critical Concepts & Methodologies as follows:

1. Understanding Context: Understanding the rules concerning security compliance and rules of the company and its impact on the use.

2. Pick out the Kind of Security Testing: The testers would then pick out the kind of security testing, after determining the security vulnerabilities and weaknesses lists in the application.

3. Testers will carry out Threat Modelling: The experience and adept testers would then carry out threat modelling, for creating a Threat Profile.

4. Next Step is to create a Test Plan: Creating a test plan to perform security testing after determining the list of vulnerabilities and potential threats.

5. Build a Traceability matrix: A traceability matrix would be created for every single identified risk or vulnerability.

6. Determination and Selection of Security Tool: Selection of a tool to be used for the testing.

7. Execute the Test Case Execution: Testers would then implement the test case after which they would detect the defects.

8. Preparing Test Case: Testers would then create the test case for the security testing.

9. Reports: The final step would be the submission of the final complete report of the security testing, which highlights the list of identified threats, flaws, and weaknesses.

In actual practice combination of several techniques may be used to have a comprehensive assessment of the complete security aspect. At ImpactQA, we provides customized security testing that aid Enterprises deal with immediate security threats to their business operations.
