Software products are complex and are equipped with multiple branches and internal API connections. As the complexity of the application increases, the need to make it free of redundancy and anomalies become evident.
In such a scenario, identifying and handling multi-faceted network errors requires robust, specific network testing tools that provide extensive statistical data that aids in having an insightful view of the application. Before progressing and discussing network test tools in detail, let’s understand the basics of network testing.
What is Network Testing?
Network testing is a technique for assessing security measures throughout a network to identify and display flaws to estimate risks. While the testing medium may vary, such as wifi, ethernet, hardware/IoT, phishing emails, physical access, and Dropbox location, the result is network access to secure data or systems. Network testing can help with any electronic data. Here are some instances of typical tests:
- Vulnerability assessment.
- Penetration checking.
- Wireless network penetration testing.
- Application security testing .
How to Choose an Ideal Network Testing Tool?
The availability of a wide range of network testing tools makes the decision of choosing an ideal tool difficult and cumbersome. These tools are available from free web-based apps to high-end suites offered by network research companies. Here are some of the factors one can consider while choosing the best network testing tool:
Look for a network testing platform with a Windows-like interface instead of a command-line or hotkey entry. A Windows environment is preferred as it reduces the initial learning cycle and supports memory storage during extended periods between usage.
Whether the user is setting up to do network testing or selecting what information to display on a report, wizards help speed up the process and minimize mistakes.
Network Testing Templates
A standard collection of network testing templates allows for faster start-up and fewer errors. The network testing templates should include regular setup, scheduling, filtering, and so forth.
Network Testing Reports
A network testing tool should quickly turn an extensive network testing database into comprehensible graphs, charts, and tables. Most clients do not want to perform a network test, take it back to the office, and then return with a report several days later. Therefore, a platform that can provide rapid and on-time reports is preferred.
Scheduling refers to the capacity to plan when data will be collected and when it will not. Avoid network testing solutions that don't have a scheduling agent and only have an "on/off" switch.
Real-time Network Testing and Analysis
This function isn't available in many network tester software. Analyzing traffic while doing network testing leads to more precise network testing and reporting.
Network Testing Management
Initial network testing provides accurate measurement and record of a network's present state of functioning. Subsequent network tests are generally carried out and compared to the first to discover whether there have been any changes. It's best to choose a network testing management system that's easy to use and takes advantage of available resources.
Network testing software should have a wide range of statistics, including analysis at the station and segment levels. The higher the number of statistics available, the more valuable the tool.
Integrated filtering narrows the focus of the sampled data gathered. As a consequence, what is necessary is collected at the appropriate time. This is especially important for collecting data from long-running network tests.
Types of Network Testing Tools
There are two types of network testing software:
1. Proprietary Network Testing Tools
For proprietary network testing software, licenses are available. These tools are available for monthly, half-yearly, and yearly pricing packages.
2. Open-source Internet Testing Tools
Open-source tools are customizable, scalable, robust, and provide organizations with a free alternative to proprietary software. Individuals and many businesses utilize and prefer open-source network testing tools to detect network issues, improve network performance, and obtain real-time insights into:
- Bandwidth utilization
- Internet hyperlinks
- The network's current state
- Unauthorized access and cybersecurity
- The network's functionality
