javascript assertion between two numbers range-CodePudding

How do I find a assertion for a value between two numbers

let lastArrayAmountValue=50;
assert.equal(lastArrayAmountValue, '5');

I want to assert whether the number is between 5-10 This is the test am doing on cypress.

CodePudding user response：

expect(lastArrayAmountValue).to.be.within(5,10)

https://docs.cypress.io/guides/references/assertions#BDD-Assertions

looks like that ability is built into cypress

CodePudding user response：

If you want to apply within to an asynchronous element, move it into .should() to trigger retry of the assertion.

For example,

cy.get(elementArraySelector)
  .last()
  .should($el => {
    const value =  $el.text() || 0; 
    expect(lastArrayAmountValue).to.be.within(5,10)  // retry until timeout
  })

You can also do like this. Number is greater than equal to 5 and less than equal to 10.

cy.wrap(lastArrayAmountValue).should('be.gte', 5).and('be.lte', 10)
