I would like to use variable Shopresult in jest test. this variable will be defined in beforeAll section.

describe("test",()=>{
    
    let Shopresult:Shop;

    beforeAll(async()=>{
        await getConnection(LocalOrmconfig).then(async()=>{
          const Shopresult = await getRepository(Shop).save(mockData)
        })
    })
    afterAll(async()=>{
        await getConnection(LocalOrmconfig).then(async()=>{
            await getRepository(PricingPattern)
            .createQueryBuilder()
            .delete()
            .where({shopId:Shopresult.shopId})
            .execute()
        })
    })
    

But above code invoked following error.

'Shopresult' is declared but its value is never read.

What is the root cause of this? I declared them in let clause.

If someone has opinion,will you please let me know. thanks

The problem is with this line. it is not using the Shopresult defined outside but creating a new variable. Remove the const keyword

const Shopresult = await getRepository(Shop).save(mockData)
