appium-wait-plugin

This is an Appium plugin designed to wait for element to be present.

Prerequisite

Appium version 2.0

Tested with appium v2.0.0-beta.42

From Verion 2.0.0

• Following bindings are not supported - sessionId/waitplugin/timeout - sessionId/waitplugin/getTimeout
• Following command are renamed - plugin: getWaitTimeout is renamed to plugin: getWaitPluginProperties - plugin: getWaitTimeout is renamed to plugin: setWaitPluginProperties

Installation - Server

Install the plugin using Appium's plugin CLI, either as a named plugin or via NPM:

appium plugin install --source=npm appium-wait-plugin

Installation - Client

No special action is needed to make things work on the client side.

Activation

The plugin will not be active unless turned on when invoking the Appium server:

appium --use-plugins=element-wait

Configuration

To override the default element-wait retry

1. Use appium server CLI --plugin-element-wait-timeout=30000 --plugin-element-wait-interval-between-attempts=200 --plugin-element-wait-exclude-enabled-check="click,clear"

2. Use appium server config file. Refer.

Example

Before wait-plugin

wait = new WebDriverWait(driver, 30);
wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("login"))).click();
wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("slider1")));
driver.findElementByAccessibilityId("slider1").click();
WebElement slider = wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("slider")));
WebElement slider1 = wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("slider1")));

After wait-plugin

driver.findElementByAccessibilityId("login").click();
driver.findElementByAccessibilityId("slider1").click();
driver.findElementByAccessibilityId("login").sendKeys('Hello');

Configure Wait timeout in test

While overriding timeouts one can choose to override all or one of the below

• timeout
• intervalBetweenAttempts

WDIO Example

await driver.executeScript('plugin: setWaitPluginProperties', [
        {
          timeout: 1111,
          intervalBetweenAttempts: 11,
        },
]);

await driver.executeScript('plugin: getWaitPluginProperties', [])

or

await driver.executeScript('plugin: setWaitPluginProperties', [
        {
          timeout: 1111,
        },
]);

await driver.executeScript('plugin: getWaitPluginProperties', [])

Java Example

driver.executeScript("plugin: setWaitPluginProperties", ImmutableMap.of("timeout", 1111 , "intervalBetweenAttempts", 11 ));

Server logs will be as below:

[Appium] Plugins which can handle cmd 'findElement': element-wait (sessionless)
[Appium] Plugin element-wait (sessionless) is now handling cmd 'findElement'
[Plugin [element-wait (sessionless)]] Waiting to find element with accessibility id strategy for login selector
[Plugin [element-wait (sessionless)]] Waiting to find element with accessibility id strategy for login selector
[Plugin [element-wait (sessionless)]] Waiting to find element with accessibility id strategy for login selector
[Plugin [element-wait (sessionless)]] Waiting to find element with accessibility id strategy for login selector
[Plugin [element-wait (sessionless)]] Element with accessibility id strategy for login selector found.
[Plugin [element-wait (sessionless)]] Checking if login element is displayed
[Plugin [element-wait (sessionless)]] login element is displayed.

Skip element Enabled Check for commands

Before performing actions such as click, setValue, clear etc, plugin waits for element to be enabled. As mentioned in #78 if there is a need to skip the elementEnabled check for a set of commands, excludeEnabledCheck can be sent along with timeout values.

Usage

wdio

await driver.executeScript('plugin: setWaitPluginProperties', [
        {
          timeout: 1111,
          intervalBetweenAttempts: 11,
	  excludeEnabledCheck: ['click','setValue']
        },
]);

await driver.executeScript('plugin: getWaitPluginProperties', [])

By default excludeEnabledCheck is empty list.
