Sahi Pro Flowcharts Action :Take Screenshot

Details

Takes a screen shot and embeds the image in the playback log.
Since Sahi works without bringing the window into focus, we first need to call _focusWindow to bring the window into focus.

_focusWindow(); // bring window into focus
_takeScreenShot();
// captures screenshot in D:\dev\capture.jpg(compresses file size to 75% of the full size with jpg format)
// without embedding image in the playback log
_takeScreenShot("D:\\dev\\capture.jpg", true, {format:'jpg', resizePercentage:75});

_takeScreenShots($enable[, $directory[, $noLog]])

_takeScreenShots(false);

Takes a full page screenshot of a web page by scrolling to the end of the page and embeds the image in the playback log. If the element attribute is specified, a full page screenshot of the browser element is taken, instead of the web page. Since Sahi works without bringing the window into focus, we first need to call _focusWindow to bring the window into focus.

_focusWindow(); // Brings window into focus
_takePageScreenShot(); // Captures the full browser page screenshot
_takePageScreenShot(_table("t4")); // Captures the table screenshot

// Captures table screenshot with jpg format, compresses file size to 75% of the full size, saves it to D:\dev\capture.jpg
// without embedding image in the playback log
_takePageScreenShot(_table("t4"), "D:/dev/capture.jpg", true, {format:'jpg', resizePercentage:75});

// Captures full div screenshot by scrolling to the end of the div.
// Use it in cases where a div has its own scrollbar.
_call(_div("myDIV").scrollIntoView()); // scroll the div into view first
_takePageScreenShot(_div("myDIV"), null, null, {mode:2}); // the div itself will be scrolled and screen shots taken

_assertSnapShot($refPath[, $element[, $differenceThreshold[, $displayOnSuccess[, $props]]]])

Takes the full page screen shot of the webpage or the browser element if specified, and compares with the reference image.
If the difference between the page screenshot and the reference image is lesser than or equal to the differenceThreshold, the images will be treated as same and the assertion is successful. Else the assertion is treated as a failure.
If the assertion is successful and displayOnSuccess is true, the page screenshot, reference image and the differential image will be embedded in the playback log.
If the assertion is a failure, _assertSnapShot will log failures to the playback log. The page screenshot, reference image and the differential image will be embedded in the playback log.

_navigateTo("http://sahi.co.in/demo/training");
_assertSnapShot("snapshot_login_page.png", _div(0), 20, true); // only _div(0) content would be compared with reference image.
// OR
_assertSnapShot("snapshot_login_page.png", null, 20, true); // passing null to compare with entire window screenshot
// OR
_assertSnapShot("snapshot_login_page.png",_div("myDIV"), 20, true, {mode:2}); // the div itself will be scrolled and screen shots taken

_compareImages($f1, $f2[, $differenceThreshold])
