Test automation is not about removing testers but to make use of their time better. It is impossible to automate testing completely, and it has to be a mix of automation and manual testing.  If you have decided to automate testing, below are some practical tips  for implementing any test automation initiative:

1. Focus on the methodology and not the tool

A clearly defined automation methodology that covers how the automation process will be conducted can eliminate most of the frustrations associated with automation by providing stakeholders with an upfront understanding. This would provide a fair idea on what is needed to automate tests, which includes tool selection as well as the rest of the automation process.

2. Choose tools that are scalable to meet future needs
