back
Go one step back in the joint session history of the current top-level
browsing context. This is equivalent to pressing the browser back button
or calling window.history.back().
The command takes no arguments and resolves with no value.
On a WebDriver BiDi session it calls
browsingContext.traverseHistory
with delta: -1 for the top-level context. A frame selected with
switchFrame does not change that target.
After the traversal is accepted, the command waits for the same document
readiness url maps from pageLoadStrategy:
nonedoes not waiteagerwaits forbrowsingContext.domContentLoadednormal(the default) waits forbrowsingContext.load
The wait uses the session page-load timeout (timeouts.pageLoad, 300000 ms
when it has not been set). A same-document traversal, such as a fragment
change, finishes without a load event. A back-forward cache restore commits
a document that is already complete and does not emit browsingContext.load;
the command returns once that document's readyState matches the strategy.
A classic session posts to the WebDriver back
endpoint. There is no previous entry in either mode when the command
rejects with no such history entry.
Usage​
await browser.back()
Example​
it('should go back and forward', async () => {
await browser.url('https://webdriver.io')
await browser.url('https://webdriver.io/docs/gettingstarted')
await browser.back()
console.log(await browser.getUrl()) // outputs the first page
await browser.forward()
console.log(await browser.getUrl()) // outputs the second page
});
