The Browse of Three Load Testing Service Tools


Load testing services aim to define and gather the systems' time response & its performance indicators in order to cover the requirements imposed on the system. 
Nearly every load testing company resorts to various load testing tools. They can be and open source, and commercial.

TestMatick test engineers browsed three handy tools for load testing service. 

#1. Joe Dog Siege 

Advantages:
- Free tool for use.
- Multithreaded.
- One can specify the number of requests and duration (time of testing). It means that it’s possible to emulate the user load.
- This tool supports the simplest scenarios.

Drawbacks: 
- Resource-intensive.
- There is a little amount of static data. Also, Joe Dog Siege doesn’t emulate very good such user scenarios as the speed limit of user requests. 
- Not suitable for serious and large-scale testing in hundreds and thousands of threads, because it is resource-intensive, and on a large number of requests and threads loads the system greatly.

#2. Tsung 

Core Capabilities:
- Written on Erlang.
- HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP, Jabber/XMPP.
- Console (GUI through a third-party plugin).
- Distributed testing (millions of users).
- Possesses the testing stages.
- Test plan – XML-file.
- Plan recording by means of Tsung recorder’a.
- Monitoring of test servers (Erlang, Munin, SNMP).
- Tools for generating statistics and graphs from logs work.

Advantages:
- Free tool.
- As it’s written in Erlang, this tool scales well but depends on the allocated resources.
- Can perform the role of a distributed system on a big number of machines.
- A great number of tested systems-not just Web servers and databases, but also, for example, XMPP-server: can send messages, tests with the authorization.
- The control via console, but, thanks to the support of plugins - can be managed by using a third-party plugin with GUI.
- The existence of Tsung Recorder tool -sort of a proxy server through which you can walk over the tested website and record as soon as the load profile.
- Generation of different testing schedules by using scripts.

Drawbacks: 
- The absence of GUI-interface.
- There is only *nix-system.

#3. WAPT

Core Capabilities: 
- Windows.
- Fee-paying (there is a trial period 30 days/ 20 virtual users).
- Record of the test plan through desktop & mobile browsers.
- Dependence on test plans (subsequent URL depending on the response from the server).
- Imitation of real users (a delay between connections, speed limit connections).

Advantages:
- Very flexible and has various configurations and tests.
- Emulation of slow user connections channels.
- The connection of modules.
- The record of test scripts straight from the browser (desktop & mobile).
- Generation of various testing schedules by using scripts.

Drawbacks: 
- Available only for Windows.
- You should pay fee to use this tool.
