Self-healing tests<\/strong> means:<\/p>\n\n\n\n

\n

Automated test scripts can adjust themselves when small changes happen in the application, especially in the UI.<\/p>\n<\/blockquote>\n\n\n\n

What does \u201clocator\u201d mean?<\/h3>\n\n\n\n

In test automation, a locator<\/strong> is how the test finds an element on the screen.<\/p>\n\n\n\n

Example:<\/p>\n\n\n\n

Click the Login button\n<\/code><\/pre>\n\n\n\n
The automation tool needs to find the Login button using something like:<\/p>\n\n\n\n
id = loginButton\n<\/code><\/pre>\n\n\n\n
or<\/p>\n\n\n\n
xpath = \/html\/body\/div\/button[1]\n<\/code><\/pre>\n\n\n\n
or<\/p>\n\n\n\n
text = Login\n<\/code><\/pre>\n\n\n\n
What problem happens?<\/h3>\n\n\n\n
Suppose the developer changes the button ID:<\/p>\n\n\n\n
Old: id = loginButton\nNew: id = signInButton\n<\/code><\/pre>\n\n\n\n
A normal automated test may fail because it cannot find loginButton<\/code>.<\/p>\n\n\n\n
But the application may still be working. The test failed because the locator changed<\/strong>, not because the feature is broken.<\/p>\n\n\n\n
Self-healing test example<\/h3>\n\n\n\n
A self-healing test may say:<\/p>\n\n\n\n
\n
\u201cI cannot find loginButton<\/code>, but I see another button with similar text, same location, and same function. It is probably the same Login button.\u201d<\/p>\n<\/blockquote>\n\n\n\n
So the automation adapts and continues the test.<\/p>\n\n\n\n
Simple classroom explanation<\/h3>\n\n\n\n
\n
Self-healing tests reduce false failures caused by small UI changes.<\/strong><\/p>\n<\/blockquote>\n\n\n\n
