Thx Sir Pavan, I am very grateful for your videos!
Welcome
now this works
Cypress.Commands.overwriteQuery(
"contains",
function (contains, filter, text, userOptions = {}) {
// This is parameter resolution from Cypress v12.7.0 source
if (Cypress._.isRegExp(text)) {
// .contains(filter, text)
// Do nothing
} else if (Cypress._.isObject(text)) {
// .contains(text, userOptions)
userOptions = text
text = filter
filter = ''
} else if (Cypress._.isUndefined(text)) {
// .contains(text)
text = filter
filter = ''
}
userOptions.matchCase = false;
let contains0 = contains.bind(this) // this line fixes the error
return contains0(filter, text, userOptions)
}
)

Unfortunately last two custom commands (overwrite/login app) result in cypress error: Cannot read properties of undefined (reading 'hasPreviouslyLinkedCommand')
I did exactly the same way as presented in the video.
i am also facing this error could you help me resolve
You can add this in the it block at the top: Cypress.on('uncaught:exception', (err, runnable) => {
if (err.message.includes('Cannot read properties of undefined')) {
return false;
}
return true;
});
Hello Sir
I am getting errors for overwriting contains() command
CypressError
The following error originated from your test code, not from Cypress.
> Cannot overwrite the contains the query. Queries cannot be overwritten.
When Cypress detects uncaught errors originating from your test code it will automatically fail the current test.
Cypress could not associate this error with any specific test.
We dynamically generated a new test to display this failure. Learn more
Hoping for your reply soon!
I have the same error.

Hey. Try to use this command for the overwrite 'contains' command:
// -- The custom command for overwriting contains() method --
Cypress.Commands.overwrite("contains", function (contains, filter, text, userOptions = {}) {
if (Cypress._.isRegExp(text)) {
// .contains(filter, text)
// Do nothing
} else if (Cypress._.isObject(text)) {
// .contains(text, userOptions)
userOptions = text
text = filter
filter = ''
} else if (Cypress._.isUndefined(text)) {
// .contains(text)
text = filter
filter = ''
}
userOptions.matchCase = false;
let contains0 = contains.bind(this)
return contains0(filter, text, userOptions)
}
)
I need your help, i writing similar command to get value from textbox by return value but not success, can you help me

@@jaminDNB Thank you Ivan :)
At time 34:41, you have added cy.wait(3000). What is the point of adding static wait when cypress supports autowait and auto synchronisation?
