Тестируем работу прокси: эффективные методы

Importance of Testing

It is necessary to verify the operation of proxies, as they are involved in many business tasks, including data collection and analysis, checking competitor websites, search engine results, social networks, and much more. Therefore, proxies are held to quite high standards, which they do not always meet. Before connecting a proxy, it is important to conduct thorough quality checks. This is one of the most critical business tasks, as it is usually not possible to do it before purchasing a proxy. Only a verified and reliable proxy can be used to ensure confidentiality, protection, and connection quality.

How to test a proxy?

Testing a proxy is easiest by simply connecting it to your own browser. Then, open an IP check service in the browser. You can connect a proxy not only in the browser but also via terminal or at the OS level by making the appropriate settings. If your address is detected as the server's address, your proxy is functioning correctly. However, such proxy functionality testing has several shortcomings:

• There is a risk of only obtaining the exit address, which can change constantly, while the entry point may not match;
• Speed, ping, and other parameters remain unknown because the browser cannot read this data;
• Information about the IP (owner/protocols/physical location) is absent;
• Inability to test additional capabilities (bypassing security systems, generating digital fingerprints, etc.);
• No information about compatibility with specific websites/services. As a result, the browser (and the terminal) provides no detailed data about the proxy, only confirming its actual operation. Using proxies professionally requires more thorough checks and more advanced tools.

Key metrics

When testing a proxy, the most important metrics are:

• response time;
• connection speed;
• anonymity;
• geolocation;
• presence on spam lists;
• compatibility with the resources and services you are interested in.

Testing methods

One effective testing method is online checkers. With them, no software installation or setup is required, and the testing process runs automatically. In the end, you only see the final result. Some checkers analyze the user's IP, while others work with server lists. The latter requires providing connection parameters. Overall, the first type of checker is good for single tests, while the second is suitable for mass checks. Another way to test a proxy is by using IP databases. This is a great alternative to lengthy checks of multiple addresses. It is important to note that these databases do not perform testing but detect proxy parameters and integrate with anti-fraud systems. Services can be free or paid with advanced options. You can test proxies using the FOGLDN Proxy Tester software for PC on any OS. Upload your list of proxies, run the check, and receive current data on working and non-working addresses, which allows you to filter them. All data remains only with you, and the testing can be tailored to target resources. The software is free, so there are risks related to what is actually written in the code. The last, most complex method is writing your own testing script. You can use ready-made templates and libraries or create code from scratch. Proxy testing is a complex task that requires considering all nuances. To avoid complicated manipulations and checks, buy proxies from trusted providers.
