Abstract: Embodiments herein may relate to, for example, a method performed by a first network node for handling a testing process associated with a third network node in a wireless communications network. The first network node obtains an instance identity of an updated or initiated third network node; and stores one or more identities of one or more UEs to be used during the testing process mapped to the obtained instance identity. Upon detection of a session establishment of a UE, the first network node checks whether an identity of the UE matches the stored one or more identities of the one or more UEs; and, with the proviso that the identity of the UE matches one of the stored one or more identities of the one or more UEs, the first network node initiates a NF discovery towards a second network node using the instance identity mapped to the matched one identity.
