SWTBot中运行中那些参数控制

Can I slow down the execution speed of SWTBot tests?

Yes you can! To slow down the speed of execution of SWTBot, you need to set the system property "org.eclipse.swtbot.playback.delay". This delay is in milliseconds. You can also set this property in code as follows:

// slow down tests
SWTBotPreferences.PLAYBACK_DELAY = 10;
// set to the default speed
SWTBotPreferences.PLAYBACK_DELAY = 0;

Can I change the timeout for execution of SWTBot tests?

Yes you can! To change the timeout, you need to set the system property "org.eclipse.swtbot.search.timeout". The timeout is specified in milliseconds. You can also set this property in code as follows:

// increase timeout to 10 seconds
SWTBotPreferences.TIMEOUT = 10000;
// set to the default timeout of 5 seconds
SWTBotPreferences.TIMEOUT = 5000;

Can I change the poll delay for evaluating conditions in SWTBot tests?

Yes you can! To change the poll delay, you need to set the system property "org.eclipse.swtbot.playback.poll.delay". The poll delay is specified in milliseconds. You can also set this property in code as follows:

// increase timeout to 1 second
SWTBotPreferences.DEFAULT_POLL_DELAY = 1000;
// set to the default timeout of 500ms.
SWTBotPreferences.DEFAULT_POLL_DELAY = 500;

         

在swtbot运行中总存在一些控制参数如超时时间,失败截屏数量等.具体请看下面不解释:
