Tech Nomads – Who Are They?

Who are Tech Nomads, and what do they do?

Based in Liverpool, Tech Nomads is a monthly meetup group. Held usually at Liverpool Science Park, this group consists of creatively minded people who are interested in programming, along with other tech and digital industry areas.

The purpose of Tech Nomads is to bring together and nurture a creative environment for people in Liverpool, to collaborate on tech-related ideas. By creating a close supportive community, Tech Nomads allows for the facilitation of creativity, through informal networking, as well as sharing ideas and experiences. Attendees can also develop their creative skills through writing code.

Recently I mentioned how the Liverpool City Region (LCR) has a growing creative, digital and tech community. Therefore, the work of groups such as Tech Nomads are indispensable, as they are hotbeds of tech and digital creativity, where like-minded people come together to meet, share, collaborate and learn from each other. It is through enabling different minds to interact in a supportive and informal environment, that creativity can thrive.

Tech Nomads is not just for people with an interest in technology. In fact, it is open to everyone, making it inclusive, open and welcoming. This is important to prevent people working in silos, which hinders creativity within organisations.

I am certainly impressed and intrigued greatly with the work that Tech Nomads does. Working in IT, I am certainly looking forward to attending events, along with meeting and networking with fellow tech enthusiasts. Finally, I am also looking forward to learning and sharing knowledge and experiences.

You can find out more about their events on Eventbrite, and also follow them on Twitter.

Liverpool Tester Gathering – Featuring Lisa Crispin

Having enjoyed and learned plenty about testing from the previous Liverpool Tester Gathering event, I was delighted to attend last week’s event at Avenue HQ. The featured speaker was Lisa Crispin, a well known and famous tester, in the world of agile testing.

Since 1982, Lisa has worked extensively as a programmer, analyst, engineer and tester, with many organisations. Therefore with such experience gained from an incredible journey, I was intrigued to learn more and I was not disappointed.liverpool_tester_gathering_sept2018_3

The event began with a lively and welcoming introduction by Leigh Rathbone from Liverpool Tester Gathering. I was greatly impressed with how Leigh introduced the evening with warmth, humour and a vibrant enthusiasm, creating an atmosphere of positive energy that swamped and caught the audience’s attention. Such an introduction certainly helped to set the feel good tone for the evening.

Listening to Lisa share her testing knowledge and experiences, there was plenty that I learned about testing simply from listening to her stories. What I learned was testing is more than just using technical tools, as it is also about human interaction, through the power of collaborative working. This is because agile testing of applications is paramount, and affects everybody who interacts with them, meaning that testing requires teamwork, collaboration and winning the hearts and minds of people. Therefore testing is the responsibility of everyone!

I also learned that testing requires the following:

  1. The courage to experiment, keep learning and push yourself.
  2. Willingness to use your beginners mind and curiosity to ask questions.
  3. Acknowledging and learning from your team and other people.
  4. Knowing when to stop testing.
  5. Understanding skills and knowledge can be transferred by asking questions, writing documentation, team activities, switching roles, video blogging and shadowing colleagues.
  6. Learning through self education including meetups, round table sessions, online courses, digital content, social media and peer learning.

Audience members also had the opportunity to take part in a lightning talk. This was a three minute slot where volunteers could talk about any subject they feel passionate about, so I took the opportunity to talk about blogging to share stories aliverpool_tester_gathering_sept2018_4nd knowledge with others. I admit I felt the nerves beforehand as giving an unscripted three-minute talk was daunting, but I kept calm and spoke clearly and to the point with confidence. It seemed to go down very well, as I received applause from the audience, and also a person asked me afterwards for advice on blogging, of which I was happy to help.

There were other volunteers who took part in the lightning talks. One talked about the importance of caring and sharing knowledge and expertise, and another talked about the importance of sharing domain business knowledge with colleagues. Such talks encapsulated the whole theme of the evening and spoke volumes of the Liverpool Tester Gathering community.

I would like to thank Leigh Rathbone, Duncan Nisbet, Chris Thacker and Philip Hughes from Liverpool Tester Gathering, for organising the event. In addition, my thanks also go to Lisa Crispin for sharing her testing expertise and knowledge, Stephen Johnson of ROQ for sponsoring the event, and to American Pizza Slice for providing such incredibly delicious pizza!

If you are interested in testing, technology or digital, I recommend these events wholeheartedly, and you can follow Liverpool Tester Gathering on Twitter and YouTube.

Liverpool Tester Gathering – API Testing Challenges with Postman & REST Assured

Development of an application programming interface (API) requires extensive testing. Such testing not only relates to the usability of an application, but also of the underlying coding mechanics, to ensure the API performs and executes the functions required.

Last week, I attended an event organised by Liverpool Tester Gathering at Avenue HQ, which looked at the challenges involved with API testing when using two specific API tools. These tools are Postman and REST Assured, which enable testers to create and customise templates, in order to test different API performance scenarios.

The event was compared by Ian Smith of ROQ, and featured two speakers in James Hattersley-Dykes and Jonny Fletcher. This event was also my first time attending, so I was looking forward to dipping my toe in the testing world. I was made to feel very welcome, as Ian opened the event by allowing me and other first-time attendees to introduce ourselves, in a warm and friendly manner.

Both James and Jonny proceeded to deliver a fascinating presentation into how Postman and REST Assured can be specifically tailored to test multiple scenarios. One of the major points that I learned early on, was there are lots of variations to consider as part of the API testing process. In addition, I also learned other useful points from James and Jonny, to consider when testing an API.

These points include the following:

  1. Important to document your API’s, as you would do your business processes.
  2. Postman is an API testing tool, which allows testers to create customised testing outputs.
  3. REST Assured is a Java-based library used for writing tailored API tests, which are understandable and human readable.
  4. User interface (UI) is suitable for testing API interface usability, but cannot sufficiently verify functions and back-end services associated with multi-user architecture.
  5. API testing is more suitable for testing automation than UI testing.
  6. In addition to API testing, it is also important to support and compliment both pre and post-testing activities.

Listening to James and Jonny speak, I was impressed with the depth of their knowledge. I not only left with a taste of what is involved with API testing, but also with a book prize that I also won, from tweeting about the event. To summarise, this event has lit the testing flame for me, and I am looking forward to hopefully attending September’s event featuring Lisa Crispin, who I believe is a legend in the Agile testing community.

In conclusion there are several I would like to thank for this event. These include James and Jonny for delivering the presentation, Ian for being a welcoming compare, and also to Avenue HQ for hosting the event. Finally I would also like to thank Doris IT for sponsoring the event, and providing the beer and delicious pizza. Doris IT is an IT recruitment company that works with talented young people from schools, colleges and universities, and develops them with many well-known organisations in the UK.
