sqlmock is not matching query, but query is identical and log output shows the same

Question

I\'m trying to write tests for some code using Gorm using sqlmock. I figured out writing tests for my insert function but now pulling my hair out trying to get an update wor

This is a strange solution but worked for me. Probably a bug in sqlmock. Duplicate your mockedRow variable and plug them in ExpectQuery.

mockedRow := sqlmock.NewRows([]string{"id", "created_at", "updated_at", "poolid"}).AddRow(1, time.Now(), time.Now(), "1")
mockedRow2 := sqlmock.NewRows([]string{"id", "created_at", "updated_at", "poolid"}).AddRow(1, time.Now(), time.Now(), "1")

        // Mock the complete transaction
        mock.ExpectQuery(`SELECT * FROM "storage_pools"  WHERE "storage_pools"."deleted_at" IS NULL AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC LIMIT 1`).
            WithArgs(c.givenPool.PoolId).
            WillReturnRows(mockedRow)

        mock.ExpectQuery(`SELECT * FROM "storage_pools" WHERE "storage_pools"."deleted_at" IS NULL AND "storage_pools"."id" = ? AND ((poolid = ?)) ORDER BY "storage_pools"."id" ASC`).
            WithArgs(1, c.givenPool.PoolId).
            WillReturnRows(mockedRow2)

Alternatively you can create an array of mockedRow as follows:

mockedRow := []*sqlmock.Rows{
sqlmock.NewRows([]string{"id", "created_at", "updated_at", "poolid"}).AddRow(1, time.Now(), time.Now(), "1"),
sqlmock.NewRows([]string{"id", "created_at", "updated_at", "poolid"}).AddRow(1, time.Now(), time.Now(), "1"),
}
And use it as WillReturnRows(mockedRow[0]) and WillReturnRows(mockedRow[1])
