Custom WebDriver Commands by TestingBot

TestingBot has added custom WebDriver commands for Chrome browsers, version 62 and higher.

We are working on making these commands available for other browsers as well.

With these custom commands, you can retrieve various metrics, throttle network speed and monitor/adjust network requests during your test.

These custom commands can be used with WebDriver's JavascriptExecutor.

Important: to be able to use these commands, you need to pass debugging: true in your desired capabilities.

Throttle Network

Description:

This call allows you to throttle network speed, or even simulate no network connection (offline-mode).

driver.execute_script("tb:throttle", "3G")
# or
driver.execute_script("tb:throttle", {
    "downloadSpeed": 10 * 1024,
    "uploadSpeed": 10 * 1024,
    "latency": 0,
    "loss": 0
})

((JavascriptExecutor) driver).executeScript("tb:throttle", "3G");
// or
Map<String, Object> throttleMap = new HashMap<>();
throttleMap.put("downloadSpeed", 10 * 1024);
throttleMap.put("uploadSpeed", 10 * 1024);
throttleMap.put("latency", 0);
throttleMap.put("loss", 0);
((JavascriptExecutor) driver).executeScript("tb:throttle", throttleMap);

$driver->executeScript("tb:throttle", ["3G"]);
// or
$driver->executeScript("tb:throttle", [
	"downloadSpeed" => 10 * 1024,
	"uploadSpeed" => 10 * 1024,
	"latency" => 0,
	"loss" => 0
]);

driver.execute_script("tb:throttle", "3G")
# or
driver.execute_script("tb:throttle", {
	"downloadSpeed" => 10 * 1024,
	"uploadSpeed" => 10 * 1024,
	"latency" => 0,
	"loss" => 0
})

browser.execute('tb:throttle', '3G')
// or
browser.execute('tb:throttle', { 
    "downloadSpeed" => 10 * 1024,
	"uploadSpeed" => 10 * 1024,
	"latency" => 0,
	"loss" => 0
})

((IJavaScriptExecutor)driver).ExecuteScript("tb:throttle", "3G");
# or
((IJavaScriptExecutor)driver).ExecuteScript("tb:throttle", "{\"downloadSpeed\":10*1024, \"uploadSpeed\": 10*1024, \"latency\": 0, \"loss\": 0}");

Options:

tb:throttle
Specifying a predefined condition

Condition	Download Speed (kb/sec)	Upload Speed (kb/sec)	Latency (ms)
`airplane` Simulate Offline Mode	0	0	0
`disable` Default - useful if you want to undo the `offline` command.	no throttle	no throttle	no throttle
`edge`	250	150	300
`3G`	400	100	100
`4G`	18000	9000	100

tb:throttle
Specify custom settings

`downloadSpeed`	`uploadSpeed`	`latency`
... kb / sec	... kb / sec	... ms

Intercept/Mock

Description:

With these commands, you can intercept and even fake responses during your test.
Blacklist requests, add/modify headers, mock responses, ...

The url parameter supports wildcard statements, for example: https://www.testingbot.com/*.

Redirect a URL

Instructs Chrome to redirect to redirect upon navigating to url.

driver.execute_script("tb:intercept", {
  "redirect": "https://www.google.com",
  "url": "https://testingbot.com",
})

Map<String, Object> interceptMap = new HashMap<>();
interceptMap.put("redirect", "https://www.google.com");
interceptMap.put("url", "https://testingbot.com");
((JavascriptExecutor) driver).executeScript("tb:intercept", interceptMap);

$driver->executeScript("tb:intercept", [
  "redirect" => "https://google.com",
  "url" => "https://testingbot.com",
 ]
]);

driver.execute_script("tb:intercept", {
  "redirect": "https://google.com",
  "url": "https://testingbot.com"
})

browser.execute('tb:intercept', { 
  "redirect": "https://google.com",
  "url": "https://testingbot.com"
})

((IJavaScriptExecutor)driver).ExecuteScript("tb:intercept", "{\"redirect\":\"https://www.google.com\", \"url\": \"https://testingbot.com\"}}");

Trigger Failure

Allows you to return a specific error for a specific request.

Possible errors:

Failed
Aborted
TimedOut
AccessDenied
ConnectionClosed
ConnectionReset
ConnectionRefused
ConnectionAborted
ConnectionFailed
NameNotResolved
InternetDisconnected
AddressUnreachable
BlockedByClient
BlockedByResponse

driver.execute_script("tb:intercept", {
  "redirect": "https://www.google.com",
  "url": "https://testingbot.com",
})

Map<String, Object> interceptMap = new HashMap<>();
interceptMap.put("redirect", "https://www.google.com");
interceptMap.put("url", "https://testingbot.com");
((JavascriptExecutor) driver).executeScript("tb:intercept", interceptMap);

$driver->executeScript("tb:intercept", [
  "redirect" => "https://www.google.com",
  "url" => "https://testingbot.com",
 ]
]);

driver.execute_script("tb:intercept", {
  "redirect": "https://www.google.com",
  "url": "https://testingbot.com"
})

browser.execute('tb:intercept', { 
  "redirect": "https://www.google.com",
  "url": "https://testingbot.com"
})

((IJavaScriptExecutor)driver).ExecuteScript("tb:intercept", "{\"redirect\":\"https://www.google.com\", \"url\": \"https://testingbot.com\"}}");

Mock Response

Allows you to return a different response (body or headers).

driver.execute_script("tb:intercept", {
  "response": {
    "statusCode": 200,
    "headers": {
       "x-a-header": "Sample"
    },
    "body": "Hello World"
  },
  "url": "https://testingbot.com"
})

Map<String, Object> mockMap = new HashMap<>();
Map<String, Object> headersMap = new HashMap<>();
headersMap.put("x-a-header", "Sample");
Map<String, Object> responseMap = new HashMap<>();
responseMap.put("statusCode", 200);
responseMap.put("headers", headersMap);
responseMap.put("body", "Hello World");
mockMap.put("response", responseMap);
mockMap.put("url", "https://testingbot.com");
((JavascriptExecutor) driver).executeScript("tb:intercept", mockMap);

$driver->executeScript("tb:intercept", [
  "response" => [
   "statusCode" => 200,
   "headers" => [
    "x-a-header" => "Sample"
   ],
   "body" => "Hello World"
  ],
  "url" => "https://testingbot.com"
]);

driver.execute_script("tb:intercept", {
  "response": {
    "statusCode": 200,
    "headers": {
       "x-a-header": "Sample"
    },
    "body": "Hello World"
  },
  "url": "https://testingbot.com"
})

browser.execute_script("tb:intercept", {
  "response": {
    "statusCode": 200,
    "headers": {
       "x-a-header": "Sample"
    },
    "body": "Hello World"
  },
  "url": "https://testingbot.com"
})

((IJavaScriptExecutor)driver).ExecuteScript("tb:intercept", "{\"response\":{\"statusCode\": 200, \"headers\": { \"x-a-header\": \"Sample\"}, \"body\": \"Hello World\" }}, \"url\": \"https://testingbot.com\"}}");

Retrieve Network Log

Description:

With the tb:network command you can fetch a log of network calls from Chrome.

driver.execute_script("tb:network")

((JavascriptExecutor) driver).executeScript("tb:network");

$driver->executeScript("tb:network");

driver.execute_script("tb:network")

browser.execute('tb:network')

((IJavaScriptExecutor)driver).ExecuteScript("tb:network");
