Validation

All @qavajs libraries use single validation system provided by @qavajs/validation package.

All validations can be negated adding not word.

to equal​

not strict equal (==)

Then I expect text of 'Element' to equal 'some text'
Then I expect '$variable' not to equal '42'

to strictly equal​

strict equal (===) (with type checking)

Then I expect text of 'Element' to strictly equal 'some text'
Then I expect '$variable' not to strictly equal '$js(42)'

to deeply equal​

deep equal (chai eql) to compare reference types

Then I expect '$variable' to deeply equal '$js({ x: 42 })'

to contain​

contain a substring

Then I expect text of 'Element' to contain 'text'
Then I expect '$variable' to contain 'text'

to match​

match a regular expression

Then I expect text of 'Element' to match '^text$'
Then I expect '$variable' not to match '$regexp'

to be above, to be greater than​

greater than

Then I expect number of element in 'Collection' collection to be greater than '3'
Then I expect '$variable' not to be above '5'

to be below, to be less than​

less than

Then I expect number of element in 'Collection' collection to be less than '3'
Then I expect '$variable' not to be below '5'

have type​

data type validation

Then I expect '$js(42)' to have type 'number'

have members​

array/object have exact members

Then I expect '$js([3, 2, 1])' to have members '$js([1, 2, 3])'

include members​

array/object includes members

Then I expect '$js([3, 2, 1])' to include members '$js([1, 2])'

have property​

have property

Then I expect '$js({ x: 2 })' to have property 'x'

case insensitive equal​

not strict equal (==) with casting to lower case

Then I expect text of 'Element' to case insensitive equal 'some text'

match schema​

match ajv schema

Then I expect '$object' to match schema '$schema'

Using in custom steps​

You can also use validations in custom steps

const { Then } = require('@cucumber/cucumber');
const { getValidation } = require('@qavajs/validation');

Then('I expect the answer {} {string}', async function(validationType, expected) {
    const answer = '42';
    const validate = getValidation(validationType);
    validate(answer, expected);
});

Poll validation​

Validation with auto-retries

const { Then } = require('@cucumber/cucumber');
const { getPollValidation } = require('@qavajs/validation');

Then('I expect the answer {} {string}', async function(validationType, expected) {
    const answer = getAnswer();
    const validate = getPollValidation(validationType);
    await validate(getAnswer, expected, { timeout: 2000, interval: 500 });
});
