React Testing #4

 # Testing in custom react hooks

 

 

 Now here is a problem if we directly use old method to get custom hook value. As, hook is not a dom element so it will throw an error. So, what we can do is use renderHook instaed of default render option

 Now after using it in above way our test passes

 

 we are using initalcount in object becayse type we assigned is object

 Act Utility

Check increment and decrement

 Now the count should be 1 but it is not so it throws an error

 We are directly calling increment so act not works ...knowmore by wathcing video again or see documentaion

 

 Codes that causes state update can't be wrapped by act so we need to manually do it

 Hello today I will be talking about 'this' keyword of javascript.It is one of the most confusing term of javascript. Since it is quite a confusion thing I will be compiling stuffs based on the materials I have learnt from the internet so as to help myself in the future. 'this' keyword can be considered quite the literal this word is English alphabet atleast for the initial understanding. Let's consider a main table of a house. It will be termed in js langauge as this.table = "main table" If we console log window.table or this.table than we will be considering the main house's table console.log(window.table) //main table Now let consider the dinning table of the house. It will be  this.dinning={ table:"dinning table"} If we want to call it will be  this.dinning.table // dinning table   Now let consider a private room and in this case it will be a function and if we want to use there we can use as mentioned below let johnsroom = { table:'j...
