![]() ![]() A Load Generator is started by its Load Generator Agent for each User Path validation. The Load Generator is a program piloted by the Controller, which plays a scenario while simulating a predefined number of users. This process extracts a link in the server response HTML code so that it can be used in the scenario.Ī list variable is a variable whose values are sourced from a specific list. The link extractor is used in a "Follow a link from the previous request" -type request. The HTTP response is the Web server answer to an HTTP request. The HTTP request is the request sent to the server to retrieve an HTML page, image or CSS file. This process extracts a form in the server response HTML code so that its values can be injected into the current request. The form extractor is used in "Submit a form in the previous request" -type requests. To use a file variable, the file from which the values will be read has to be configured. These credits are used to start Cloud sessions a credit is consumed every hour while a session is open.Ī file variable takes its values from a file with a format such as a comma separated values (CSV) file. In this case, its Load Generators IP addresses will be available from the availability date, although the Load Generators cannot be used for testing until the start date.Ī Cloud workgroup is made up of a number of technical or administrative contacts, plus the credits available, reserved and used. ![]() A Cloud session also may have an availability date that pre-dates its start date. It starts at a start date and stops at a scheduled end date. The information is sent as plain text (merely base64 encoded) in the Authorization header.Ī Cloud Load Generator is special in that it is hosted on a virtual machine at a Cloud hosting service provider.Ī Cloud session can contain several Cloud Load Generators in several geographical zones. Within the context of an HTTP transaction, basic authentication is an operation whereby the browser includes user account information (login and password) in a request. Other than clearly pointing out unexpected or faulty behavior in load scenarios, assertions and assertion errors also reveal functional issues. NeoLoad and Neotys Design Studio can be configured to throw assertion errors when the conditions defined by an assertion are not met. Validation can be based on the response content, size or duration. This is a C library to encode ASCII string to base64 format and decode base64 string to ASCII.Validates a server response during a test by defining and asserting a condition that must be met. Groups of 6 bits (6 bits have a maximum of 26 = 64 different binary values) are converted into individual numbers from left to right (in this case, there are four numbers in a 24-bit string), which are then converted into their corresponding Base64 character values. These three values are joined together into a 24-bit string, producing 010011010110000101101110. Encoded in ASCII, the characters M, a, and n are stored as the bytes 77, 97, and 110, which are the 8-bit binary values 01001101, 01100001, and 01101110. In the above quote, the encoded value of Man is TWFu.

For example, MIME's Base64 implementation uses A– Z, a– z, and 0– 9 for the first 62 values. This combination leaves the data unlikely to be modified in transit through information systems, such as email, that were traditionally not 8-bit clean. The general strategy is to choose 64 characters that are both members of a subset common to most encodings, and also printable. The particular set of 64 characters chosen to represent the 64 place-values for the base varies between implementations. Each base64 digit represents exactly 6 bits of data. The term Base64 originates from a specific MIME content transfer encoding. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. ![]()
