Despite the ongoing pandemic, it’s been business as usual at CodeScreen, and we have been working hard on building out new product features.

Here is a quick overview of what we released during April:

Code Coverage Reports:

We are now including code coverage analysis in the final report we generate for every candidate’s solution.
Code coverage metrics indicate the percentage of the candidate’s solution that is covered by test cases.

We calculate two code coverage metrics:

  1. Branch Coverage:
    The percentage of branches of each control structure (such as if and case statements) that have been executed during the test suites run.
  2. Line Coverage:
    The percentage of statements that have been executed during the test suites run.

This allows you to quickly see how thoroughly each candidate can test the code that they write, which is a critical skill to have in modern-day software development.

GraphQL Support:

GraphQL has gained significant traction since being released to the public in 2015. It is often presented as a revolutionary new way to think about APIs.

As it’s popularity has increased, so to as the demand for developers with GraphQL experience & knowledge. As a result, there is now an increased need for assessments that test this knowledge.

We have released new GraphQL assessments the follow the same pattern as our existing assessments that involve REST APIs, i.e., query some data from a GraphQL endpoint and calculate some statistics about the returned data:

Going forward, for new assessments we release that involve REST APIs; we will also provide corresponding assessments that use GraphQL APIs.

New React Tests:

We have seen a large number of requests for React assessments in the last few months. While we have supported creating custom React assessments for a while now, we released our first batch of React off the shelf assessments this month.

Unlike more traditional React tests that ask questions such as
“What is a prop?”, our assessments involve the candidate having to modify existing React apps to implement/extend certain functionality.

This type of assessment completely mimics the work the candidate will be doing if they were to come work for you as a React developer.
