Keysight Elastic Network Generator is a key component of a new end-to-end network test platform based on open standards that enables testing and validation of network products, network designs, and network configurations in an emulated replica of a data center network. This new open platform provides a virtualized digital twin and containerized test tools to accelerate network validation without the need to utilize real network hardware for replicating physical network topologies in a lab.
In this test drive, you can explore the power of Keysight test tools to validate modern data center networks in a software world. This test drive includes both the free version 'Ixia-c' and the commercial version 'KENG.' This lab introduces the concept of Network Topology Emulation through the Container Lab software. In this test drive, you can run four labs: two using the Ixia-c tool and two using Keysight Elastic Network Generator (KENG).
Keysight Elastic Network Generator is a modern test tool with a brand-new architecture based on containers / micro-services / open-source interfaces and can be deployed inside a multitude of software environments. Thanks to its modular design which includes few mandatory elements and several optional elements, those environments can range from a small-scale device test running on a laptop to a large scale complex network validation running in any private or public cloud.
The basic environment required to operate the tool consists of a Linux Host running Container Engine software. The traffic generated by the tool can be sent directly over the Linux Host Ethernet interfaces or it can be directed towards various overlay networks. However, many of these network connections cannot forward all routing protocol frames and they prevent the correct execution of the test scripts. What is needed is a direct virtual link between all containers involved in the test which can transport any frame generated by the containerized network devices.
Most of the vanilla container orchestration tools do not have sufficient capabilities to create such a direct link. Therefore, various solutions for large scale Network Emulation in a containerized environment have been designed. These solutions oversee orchestrating the test tool containers along with the network device containers, creating virtual links between these elements as required by the network topology, and isolating the whole test environment from other similar test environments. Examples of such Network Emulation solutions include Container Lab or Kubernetes Network Emulation and Keysight Elastic Network Generator is seamlessly integrated with both these ecosystems.
Zero trust bases security on identity not perimeter and restricts any lateral network movement. Validating this complex infrastructure is challenging, so a completely new way to test network application and security is necessary.
In the rush to move to cloud networks, organizations are finding difficulty in rightsizing cloud and optimizing cost while minimizing user disruptions. Testing the performance of elastic environments and isolating bottlenecks is also challenging.
Cloud excellence involves proficiently using, managing, and optimizing cloud resources to deliver value to businesses and end-users. As reliance on cloud services grows, measuring and quantifying excellence becomes crucial for optimal outcomes.
Take advantage of this unique opportunity to harness the power of Keysight Cyperf and steer your cloud operations toward unbridled excellence. Join our test drive and pave the way for an adequate and exemplary cloud infrastructure.
Generate authenticated and unauthenticated application traffic and security attacks to validate zero trust authentication policies. Characterize the performance, scale, and responsiveness of the zero trust implementations by generating thousands of authentication requests and concurrent sessions repeatedly.
Recreate every aspect of a realistic workload across a variety of physical and cloud environments. Easily validate your software-defined wide area network (SD-WAN) solutions by measuring bandwidth performance and QoE of various topologies, along with the effectiveness of your security deployment.
Validate security efficacy and performance impact of your secure access service edge (SASE) offerings. Recreate attacks like exploits, malware, and advanced threats across physical and cloud environments to gain valuable insights into user experience, security posture, and performance bottlenecks.
Benchmark application performance of cloud instances that traverse switches, internet gateways to other cloud locations (multi-cloud topologies), or on-premise environments (hybrid topologies). Use elastically-scaling tests to accurately measure the performance and security impact of elastic scale up or down.
Test web application firewall (WAF) performance and security effectiveness with realistic attack simulations. Balance quality of experience (QoE) with network security by validating the ability of your WAF to block attacks, such as the OWASP Top 10, while allowing legitimate traffic to pass through uninterrupted.
I am trying to do property-based testing using ScalaTest. I have written a few test cases using 2 custom generators and they work fine. However, the moment I define a forAll with one custom generator, such as below:
type mismatch; found : (org.scalacheck.Gen[A], DataGeneratorTest.this.PropertyCheckConfigParam*) required: ?0C[?0E] Note that implicit conversions are not applicable because they are ambiguous: both method ArrowAssoc in object Predef of type [A](self: A)ArrowAssoc[A] and method Ensuring in object Predef of type [A](self: A)Ensuring[A] are possible conversion functions from (org.scalacheck.Gen[A], DataGeneratorTest.this.PropertyCheckConfigParam*) to ?0C[?0E]

I ran into the exact same issue and found that there was a conflict with using the Inspectors trait along side the PropertyChecks trait. After removing the Inspectors trait from my test class, everything worked fine.
Rails generators are commonly used to create and/more modify project files in a Rails project. Setting up a Rails project with a Service Worker in the Rails asset pipeline can be a bit involved, and using the Rails generator to take care of the boilerplate makes it more convenient to get up-and-running with the gem.
Though this is a testing post but I'll briefly mention some resources I've found helpeful for writing Rails generators. I recommend the Rails guides to get your Rails generator started. It also help to understand how Thor works (What is Thor?), the library on which most Rails commandline tools are based. The Rails generator base classes leverage Thor actions, i.e., create_file, gsub_file, insert_into_file, and sprinkle in some Rails-specific methods, including gem, rake, initializer, etc.
Without consulting an external library for "testing Rails generators", I wanted to take a pass at figuring it out on my own. I'd need to run the generator in the tests to verify the output and that the generator is working. This means the tests would have side effects that modify the file system.
When using database access in tests, we typically expect to wipe test database clean before each test either by truncating or rolling back transactions. Modifying the file system is pretty much the same thing we're trying to do with testing a Rails generator: trigger some side effects, wipe the slate clean, repeat.
Since the serviceworker-rails generator adds and modifies files in a Rails app, I decided I needed to generate a fresh Rails app while running the tests and delete it after the tests finish. Crazy, right? I ended up with a test helper that generates the app with something like this:
Skipping all those features simplified things a bit, but still, creating and destroying a temporary Rails app for each test was overkill so I decided to generate the Rails app once, before all the tests were run. Since I use MiniTest for serviceworker-rails, the test setup looked like this:
Though what I came up with worked and didn't rely on any third-party dependencies, I wasn't totally happy with it. The tests were very verbose. I didn't like that I had to shell out to run the generator. I finally decided to "peek" and see how Rails tests its own generators, you know, the ones you love for generating models, migrations, and entire resource scaffolds.
It turns out Rails generators are tested using Rails::Generators::TestCase. Since Rails tests are also written in MiniTest and my library already relies on Rails as a dependency--it is a Rails engine--making the switch in my tests easy. If you're using RSpec, I did come across ammeter, which delegates to Rails::Generators::TestCase under the hood, so it'd be quite similar to what I did here.
Doing so brings in a bunch of helper methods for configuring the destinationdirectory, running the generator, and conveniences for making assertions on the generatedfiles. We declare the generator under test and a destination:
The run_generator method will instatiate the generator class and execute it inthe configured destination directory within the test process (no shell command, yay!). The test case class does provide a setup macro to ensure the destination directory exists:
However, this method makes no assumptions about what I want to modify in thatdirectory, so as far as I could tell, I still needed to generate the rails appin the destination directory and clean it up after the test run. I ended upkeeping the approach I had used previously:
The complementary assert_no_file method is useful for ensuring a file was not created under certainconditions. There is also asset_migration and assert_no_migration forverifying migration files without having to know the migration timestamp tolocate the file by absolute path.
