Q1Domain Verified
Within the context of "The Complete Jest Matchers & Assertions Course 2026," which matcher would be the most conceptually appropriate for asserting that an object contains a specific nested property and that its value matches an expected primitive, while also being robust against other properties of the object?
`toHaveProperty()`
`toBe()`
`toMatchObject()`
`toEqual()`
Q2Domain Verified
Considering the advanced topics in "The Complete Jest Matchers & Assertions Course 2026," when would you strategically choose `toStrictEqual()` over `toEqual()` for asserting array equality, and what potential pitfall does it guard against?
When the array is expected to be empty, and you want to assert that it has no length and no properties.
When the order of elements is critical, and you want to ensure no extra properties are present on the array objects themselves or their contained elements.
When the array contains primitive values, and you need to ensure strict type equality for each element.
When the order of elements in the array is irrelevant, and you want to ensure no extra properties are present on the array objects.
Q3Domain Verified
In "The Complete Jest Matchers & Assertions Course 2026," the course emphasizes understanding the nuances of asynchronous assertions. Which of the following scenarios most accurately reflects a situation where `resolves.toStrictEqual()` would be the superior choice compared to `resolves.toEqual()`?
Asserting that a promise resolves to an array where the order of elements is unimportant, and extra properties on nested objects are acceptable.
Asserting that a promise resolves to a primitive value with strict type equality.
Asserting that a promise resolves to an array with the same elements in any order, but the resolved objects should not have unexpected extra properties.
Asserting that a promise resolves to an object with specific nested properties and their exact values, ensuring no additional properties exist on the resolved object or its nested structures.
