class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"538\" data-end=\"717\">In most <a href=\"https:\/\/www.testleaf.com\/blog\/is-chatgpt-changing-the-game-in-test-case-writing\/\">test cases<\/a>, if an assertion fails, the test stops immediately.<br data-start=\"608\" data-end=\"611\" \/>But what if you want to <strong data-start=\"635\" data-end=\"677\">validate multiple fields or conditions<\/strong>, and see <strong data-start=\"687\" data-end=\"716\">all the failures together<\/strong>?<\/p>\n<p data-start=\"719\" data-end=\"760\">That\u2019s where <strong data-start=\"732\" data-end=\"751\">soft assertions<\/strong> come in.<\/p>\n<h3 data-start=\"762\" data-end=\"794\">What is a Soft Assertion?<\/h3>\n<p data-start=\"795\" data-end=\"914\">A soft assertion lets the test <strong data-start=\"826\" data-end=\"846\">continue running<\/strong> even if one of the checks fails.<br data-start=\"879\" data-end=\"882\" \/>It\u2019s perfect for scenarios like:<\/p>\n<ul data-start=\"915\" data-end=\"1040\">\n<li data-start=\"915\" data-end=\"948\">\n<p data-start=\"917\" data-end=\"948\">Validating all fields on a form<\/p>\n<\/li>\n<li data-start=\"949\" data-end=\"998\">\n<p data-start=\"951\" data-end=\"998\">Checking multiple UI components after an action<\/p>\n<\/li>\n<li data-start=\"999\" data-end=\"1040\">\n<p data-start=\"1001\" data-end=\"1040\">Comparing several values in a dashboard<\/p>\n<\/li>\n<\/ul>\n<p>Example:<\/p>\n<blockquote><p><em><strong>await expect.soft(locator1).toHaveText(&#8216;Welcome&#8217;);<\/strong><\/em><br \/>\n<em><strong>await expect.soft(locator2).toBeVisible();<\/strong><\/em><br \/>\n<em><strong>await expect.soft(locator3).toHaveValue(&#8216;John&#8217;);<\/strong><\/em><\/p><\/blockquote>\n<p data-start=\"1225\" data-end=\"1360\">Instead of stopping at the first failure, Playwright will <strong data-start=\"1283\" data-end=\"1320\">collect all the assertion results<\/strong> and report them at the end of the test.<\/p>\n<h3 data-start=\"1367\" data-end=\"1378\">Tip:<\/h3>\n<p data-start=\"1379\" data-end=\"1524\">You can mix <code data-start=\"1391\" data-end=\"1401\">expect()<\/code> and <code data-start=\"1406\" data-end=\"1421\">expect.soft()<\/code> in the same test if needed.<\/p>\n<p data-start=\"1531\" data-end=\"1648\">Soft assertions help you get a <strong data-start=\"1562\" data-end=\"1595\">full picture of what&#8217;s broken<\/strong>, especially during regression testing or UI reviews.<\/p>\n<p><a href=\"https:\/\/www.testleaf.com\/all-courses.html\"><img decoding=\"async\" class=\"aligncenter wp-image-4599 size-full\"
