How can i use soft assertion in Cypress - automation

Question

I have configured soft assert from npm (npm i soft-assert) and now my package.josn has "soft-assert": "^0.2.3"
i want to use function of Soft assert
softAssert(actual, expected, msg, ignoreKeys)
But don't know, what is the exact steps to use it
Example:
When i use soft assertion function in my code, getting following error.
If i use like this
cy.softAssert(10, 12, "expected actual mismatch and will execute next line") : not supported
or if i use different way like
softAssert(10, 12, "expected actual mismatch and will execute next line") : SoftAssert not defined
Can any one tell me how to use this 'softAssert' function in cypress code with some small example?
Now the problem I am facing
it('asserts and logs and fails', () => {
Cypress.softAssert(10, 12, "expected actual mismatch...");
cy.log("text")
Cypress.softAssertAll();
})
I need my code after soft assertion as cy.log("text") to be executed in the same 'it' block but the current test failing the whole 'it' block, without executing 'cy.log("text")' statement.

The soft assertion concept is pretty cool, and you can add it with minimal implementation to Cypress
const jsonAssertion = require("soft-assert")
it('asserts several times and only fails at the end', () => {
jsonAssertion.softAssert(10, 12, "expected actual mismatch");
// some more assertions, not causing a failure
jsonAssertion.softAssertAll(); // Now fail the test if above fails
})
To me, it would be nicer to see each soft assertion failure in the log, so it's possible to add custom commands to wrap the soft-assert functions
const jsonAssertion = require("soft-assert")
Cypress.Commands.add('softAssert', (actual, expected, message) => {
jsonAssertion.softAssert(actual, expected, message)
if (jsonAssertion.jsonDiffArray.length) {
jsonAssertion.jsonDiffArray.forEach(diff => {
const log = Cypress.log({
name: 'Soft assertion error',
displayName: 'softAssert',
message: diff.error.message
})
})
}
});
Cypress.Commands.add('softAssertAll', () => jsonAssertion.softAssertAll())
//-- all above can go into /cypress/support/index.js
//-- to save adding it to every test (runs once each test session)
it('asserts and logs but does not fail', () => {
cy.softAssert(10, 12, "expected actual mismatch...");
cy.log('text'); // this will run
})
it('asserts and logs and fails', () => {
cy.softAssert(10, 12, "expected actual mismatch...");
cy.log('text'); // this will run
cy.softAssertAll();
})
