NeoLoad Technical Features

Test Scenario Design

Scriptless Design and Visual Programming

Loops, conditions and other “drag & drop” controls simplify test design creation, and Javascript can still be used for extremely advanced cases.

Powerful Extractors

Easily define advanced data extraction rules and save time by validating them against recorded content before running the test.

Check User Paths

Quickly check a user path against a new version of the application under test to identify changes that may cause errors.

Prefilled Transaction List for Recording

NeoLoad provides a pre-filled list of transactions to make the recording process faster. Pick from current user paths or upload transaction names from a CSV file.

Record Mobile Applications

Record any mobile application (native, hybrid or mobile browser) directly from any mobile device with the proxy mode or DNS tunnel mode.

Shared Elements

Share business or technical building blocks among several user paths.

Broad Technology Support

NeoLoad has dedicated support for recording all the latest web technologies like HTML5, Push, WebSocket, AngularJS, Oracle Forms and many more.

See the full list of supported technologies.

Advanced Correlation

Smart extraction of data and dynamic links from pages for variabilization in the performance testing scenario, with no need for scripts:

  • Pre-defined rules for the most common frameworks: .Net, JSF, Oracle E-Business, SAP Web and more
  • Automatic detection and handling of application-specific parameters

User Path Update

Quickly update a designed user path with a new recording and automatically keep variable extractors, think times, SLAs, loops, javascript, validations and more from the original user path design. Merely follow the User Path Update wizard to guide you through matching up the transactions between the new recording and old recording, check that everything is merging, adding or deleting correctly, and NeoLoad handles the rest.

Record Here

Insert a partial recording into an existing user path.

Web Secure Ready

Supports SSL and Kerberos, NTLM, Basic, Digest authentications, or authentication by client certificates.
