The Transaction Test Type will be retired on March 1, 2026. We recommend transitioning any Transaction tests to Playright or Puppeteer, and have introduced a script converter to assist you. Learn More.
Catchpoint provides support for multi-step browser automation testing in multiple languages. This article focuses on the Transaction test type, which is compatible with the Selenium language. Additionally we offer support for Playwright and Puppeteer, via those respective Test Types. We recommend Playwright and Puppeteer, as these languages are more modern browser-automation tools.
The Catchpoint Transaction Test enables you to run scripts written in Selenium language to continuously monitor Web Applications. If you are comfortable with the Selenium Language you can write your scripts, but it is also possible to record a web transaction in Selenium Language and copy the resulting script into the Transaction Test configuration.

| % Adjusted Availability | Ignoring any purged runs, the percentage of test runs where the primary URL server was reached and the test was completed (i.e. there was not a Test Error.) |
| % Availability | The percentage of test runs where the primary URL server was reached and the test was completed (i.e. there was not a Test Error.) Availability is calculated as: (# Test Runs - # Test Errors) / # Test Runs |
| % Content Availability | The percentage of time that all the elements on the webpage were available. Content Availability is calculated as the number of times the test ran successfully with no loading errors, divided by the total number of times the test ran. If at least one object failed to load during testing, that test run is regarded as having content that failed to load properly. |
| % Downtime | The percentage of test runs where the primary URL server was unavailable, unreachable, or otherwise failed (i.e. there was a Test Error.) Downtime is calculated as: # Test Errors / # Test Runs |
| % Frustrated | The percentage of test runs that exceeded the Apdex “frustrated” threshold. |
| % Not Frustrated | The percentage of test runs that completed in less time than the Apdex “frustrated” threshold. This is equivalent to: % Satisfied + % Tolerating |
| % Ping Packet Loss | The percentage of pings packets sent which did not receive a response. Calculated as: (# packets received / # packets sent) * 100 |
| % Satisfied | The percentage of test runs that completed in less time than the Apdex “Satisfied” threshold. |

| % Tolerating | The percentage of test runs that exceeded the Apdex “Satisfied” threshold but completed in less time than the “Frustrated” threshold. |
| Apdex | A scoring mechanism that translates performance metrics of diverse applications into generic “User Satisfaction” levels using predefined response time thresholds. You can use default Apdex thresholds or configure your own on a per basis. For more details about Apdex, visit http://www.apdex.org/ |

| Connect (ms) | The time it took to establish a TCP connection with the server. |
| Content Load (ms) | The time it took to load the entire content of the webpage after the connection was established with the primary URL server. This is the time from the end of Send (ms) until the final element, or object, on the page was loaded. |
| CSS (ms) | Total time spent loading CSS files, in milliseconds. |
| CSS Bytes | Total size of CSS files downloaded during the test, in bytes. |
| Cumulative Layout Shift | Measures the unexpected shifting of webpage elements while the page is still loading. CLS looks at the proportion of the viewport that was impacted by layout shifts and the movement distance of the elements that were moved. |
| DNS (ms) | The time it took to resolve the domain name to an IP address. |
| Document Complete (ms) | The time it took from the initial URL request being issued until the browser triggered the "onload" event. Any inline requests or requests inserted via "document.write" must complete loading before the event is fired. Document Complete does not account for dynamic requests that may be generated later via JavaScript and/or DOM manipulation. |
| DOM Load (ms) | The time it took to load the Document Object Model (DOM) for the webpage. |
| Downloaded Bytes | The total number of downloaded bytes from the primary URL of the test(s). |

| Ping Round Trip (ms) | Average time between sending a ping packet and receiving a response. |
| Redirect (ms) | Time from the start of navigation to the end of the last Redirect. |
| Render Start (ms) | The time from initial navigation until the first visual content is painted to the browser display. |
| Response (ms) | The total time from the initial request until receiving the last packet of response data. It is the sum of DNS + Connect + ssl + Send + Wait + Load for all elements. |

| Send (ms) | The time it took to send the request to the server. |
| Server Response (ms) | The time from when DNS was resolved to receiving the last response packet from server. (This shows the server response exclusive of dns times) |
| Signal Quality | Measures the quality of the WLAN connection in terms of data transfer speed. It indicates what percent of the available network are you using to move data (upload / download). 99% is as good as it gets in terms of signal quality. |
| Signal Strength (dBm) | This number represents the power the clients device is receiving from the Access Point / Wi-Fi router. A number of -30 dBm indicates excellent while a number of -70dBm indicates very poor signal strength. |
| Speed Index | A calculated metric that represents how quickly the page rendered the initial user-visible content above the fold. A lower Speed Index indicates faster rendering of visible content. |
| SSL (ms) | The time it took to complete the ssl handshake with the server. |
| Test Time (ms) | One cohesive metric that applies to all test types and indicates the total duration of the test run. Test Time is equivalent to Response, Test Response (Transaction and web tests) and ping RTT (Trace Route tests), and is used when calculating Apdex. Test Time is not available for Request, Host, or Zone charting. |
| Throughput | Measures how efficiently the system was able to retrieve all elements in kilobytes per second. Throughput is calculated as follows: Throughput = Size / Time where: Size = (FileSize + HeaderSize)/1024 *converts from bytes to KBs Time = (Wait + Load)/1000 *converts from ms to seconds |
| Time To First Byte (ms) | The total time from the initial DNS request to receiving the first response packet from the server. This is calculated as: |
| Time To Interactive | The time when the page first became interactive. TTI marks the point at which the webpage is both visually rendered and capable of reliably responding to user input. |

| Webpage | |
| Webpage Throughput | Measures how efficiently the system downloaded the content of the entire webpage. Webpage Throughput is calculated as: (File Size + Header Size) / Webpage Response (ms) |
| Wire Time (ms) | The total amount of time where at least one request was on the wire, from the start of the test or step to Document Complete. |
| XML (ms) | Total time spent loading XML files, in milliseconds. |
| XML Bytes | Total size of XML files downloaded during the test, in bytes. |
