Intuitive enough and easy to learn, but in terms of folder organization, it could be better
Inflectra SpiraTest is the new kid on the block compared to Jira and Azure. Still, when I started exploring the tool, I realized that it was no different from other tools I've used in the past, but it all boils down to adaptability because the features would always be more or less the same. I found Inflectra SpiraTest intuitive enough. It's also easy to learn, so this is what I like about it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"3SL Cradle's most valuable feature is its flexibility in managing all your needs immediately."
"3SL Cradle enabled my current and former organizations to be champions of requiring and providing bi-directional traceability to all relevant data, from cradle to grave -- the entire project lifecycle -- due to the tool’s ability to be customized with ease and ability to produce products that builds confidence in project stakeholders."
"I found Inflectra SpiraTest intuitive enough. It's also easy to learn, so this is what I like about it."
"Once you have learned it (it has so much functionality), it's quite easy to do a lot of things."
"With this tool, we were able to make our software testing life cycle more efficient as well as create more transparency."
"Inflectra SpiraTest has a lot of functionality, which is good."
"The most valuable thing is that it's a test management system, in which you can handle a mass of test case specifications and executions."
"It has helped our company to centralise our testing efforts and create better visibility into our testing."
"It's a good product with an exceptionally low cost."
"The user-friendly features are the most valuable. For example, migration of requirements and migration of test cases and the creation of traceability. You have various reports that you need. The plug-ins that are available to connect with the other tools."
 

Cons

"Cradle provides around 15 modeling notations (e.g. Data Flow Diagrams, State Transition Diagrams, Use Case Diagram, etc.); however, SysML and DoDAF are not included."
"3SL Cradle could be improved with better support for SysML functionalities."
"Two areas that can stand improvement: integration with third party products and making it more intuitive."
"The deciding factor to not use SpiraTest anymore was because it was cumbersome to integrate with TFS."
"Areas of improvement are all minor things to streamline the process of setting up a release."
"The UI for managing test cases, test sets, test runs could be a little more integrated, currently, these feel disjointed at times and confusing. Also, the test steps page needs to display the test steps closer to the top of the UI so as to not have to scroll down to find."
"One of the main issues encountered was around scalability."
"Migrating is not very easy. It depends on the organization, how efficient and effective the decision-making process is. The plug-ins should be easier and more integrated rather than the user trying to integrate the tools which are more popular, like Jira et al."
"Yes, I noticed in my previous job, as one generates many test reports, database access becomes very slow to the point of being unusable."
"Customizing test reports seems to be something one must have (or gain) expertise in."
