Three Tips for Writing CDK Tests
Tags: aws, awscdk, testing, learning
Published: 2024-03-18 12:25:22

## 1. Use the assertions module

Something of a no-brainer, but use the tools you’re given! One of the best parts of the CDK library is the assertions module. It contains two sections. One for “fine-grained” assertions, like what you would write during unit testing. The other is for performing “snapshot” tests, in which you compare the new template against one that is already deployed. It’s a section of the library that can be easily missed but provides so much value when used correctly.

## 2. Make any Nested Stacks easily accessible

One of the benefits of using CDK is the ability to create declarative dependency trees. But, testing the implemented Nested Stacks can be tricky. One of the best ways I’ve found to simplify this is to add Nested Stacks as properties of the Stack class that handles deploying them. For example…

```ts
import SubStack from 'substack-stack.ts';

export class TopStack extends Stack {   
  constructor(scope, id, props) {     
    const subStack = new SubStack(this, 'substack', props);   
  } 
}
```

Is pretty standard. While it is possible to test this, you can simplify the process by “stashing” a reference.

```ts
import SubStack from 'substack-stack.ts';

export class TopStack extends Stack {   
  subStack: SubStack;    
  constructor(scope, id, props) {     
    this.subStack = new SubStack(this, 'substack', props);   
  } 
}
```

Now accessing this for fine-grained assertions can look like…

```ts
import { Capture, Match, Template } from "aws-cdk-lib/assertions";
import * as cdk from "aws-cdk-lib"; 
import { TopStack } from "top-stack";  

describe("TopStack", () => {   
  test("has the substack", () => {     
    const app = new cdk.App();      
    const topStack = new TopStack(app, "topStack", {});     
    const { subStack } = topStack; // we pull the substack through the property      

    // Pass the subStack to template.     
    const template = Template.fromStack(subStack);   
  } 
}
```

## 3.  Write your template to a file (sometimes)

While writing assertions, you can find situations where the tests are failing for reasons that may not make sense. When this happens, one of the first things I will do is write the CloudFormation template out into a file. This way you can get a cold hard copy of what it is you are building in your hand. Rather than trying to parse through complex logs or mysterious error messages. Not a guarantee but often getting to see the complete output can solve many common testing pitfalls.

## Conclusion

Testing is great! Testing your infrastructure… Even better! If you’re just getting started with CDK or if you’ve been around since the early days, I hope these tips can help you along your journey! If you have any tips you'd like to add, share them in the comments. Always looking to learn more!

Setup MFA Delete in S3 bucket
Published: 2024-03-18 12:15:27


## **Setup MFA Delete in S3 bucket**

Enabling MFA (Multi-Factor Authentication) delete functionality on an S3 bucket helps prevent accidental deletion of files.

Step to enable MFA delete on S3 bucket.

 1. Make sure S3 bucket version is enabled.

![](https://cdn-images-1.medium.com/max/2000/1*3h4B40EoF5ZIhuWzyRVRUg.png)

2. Below CLI command to enable MFA delete

aws s3api put-bucket-versioning — bucket s3 bucket name — versioning-configuration Status=Enabled,MFADelete=Enabled — mfa “:aws:iam::(accountnumber):mfa/root-account-mfa-device (pass)”

(pass) -> This is six digit passcode from your MFA device configured.

Once MFA delete is enabled verify the settings inside S3 Bucket -> Properties -> Bucket Versioning.

Redis Cache in .NET
Published: 2024-03-18 11:33:01

Hello guys!

Today I'll demonstrate how to implement Redis Cache in a .NET project.

## What is Redis Cache?
Redis is an open source (BSD licensed), in-memory data structure store that can be used as a database, cache, message broker, and streaming engine.

## Why Redis?

- All Redis data resides in memory, which enables low latency and high throughput data access. Unlike traditional databases, In-memory data stores don’t require a trip to disk, reducing engine latency to microseconds. Because of this, in-memory data stores can support an order of magnitude more operations and faster response times.

- Easy to use.

- High availability and scalability.

- Open Source.

- Flexible data structures.

## **Step 1**
You need to configure your Redis server. For that you can download and run an image of Redis in a docker container.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ytgm0laj7jbo6pqtggxf.png)


## **Step 2**
Once your Redis server is up and running you need to install the following nuget package
```
Microsoft.Extensions.Caching.StackExchangeRedis
```

## **Step 3**
On the ConnectionStrings section of the appsettings.json file, add the following entry

```
 "ConnectionStrings": {
    "Redis" : "localhost:6379"
  },
```

## **Step 4**
Then you need to configure your connection to the Redis server in the `Program.cs` file

```
builder.Services.AddStackExchangeRedisCache(redisOptions =>
{
    string connection = builder.Configuration.GetConnectionString("Redis");
    redisOptions.Configuration = connection;
});
```

## **Step 5**
On your controller, you'll need to inject `IDistributedCache `via Dependency Injection.

```
        private readonly IDistributedCache? _cache;

        public TvShowsController(TvShowContext context, IDistributedCache cache)
        {
            _context = context;
            _cache = cache;
        }
```

## **Step 6**
Finally is time to store and retrieve values to and from your Redis Cache.

```
[HttpGet]
        public ActionResult<IEnumerable<TvShow>> GetTvShows()
        {
            string cachedData = _cache.GetString("cachedData");
            if (string.IsNullOrEmpty(cachedData))
            {
                var tvShows = _context.TvShows.ToList();
                string serializedObject = JsonConvert.SerializeObject(tvShows);
                _cache.SetString("cachedData", serializedObject, new DistributedCacheEntryOptions() { AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(10) });
                return tvShows;
            }

            return JsonConvert.DeserializeObject<List<TvShow>>(cachedData);
        }
```

Go Woo-seok, LG also gave 2 runs, Opening roster red light
Published: 2024-03-18 11:37:08

Ko Woo-suk (25) took the mound at Gocheok Sky Dome wearing the San Diego Padres uniform. However, the reality was harsh. He was criticized by LG Twins hitters, who are close to him, and allowed two runs. Due to repeated poor performances since exhibition games, a red light was turned on to enter the opening roster.

In a special match against LG at Gocheok Sky Dome in Seoul at noon on the 18th, Ko took the mound as relief pitcher in the ninth inning, allowing two hits (one homer) and two strikeouts and two runs in the first inning. His team won 5-4 to post a save, but gave up multiple runs, leaving him anxious.

Having settled in San Diego through a posting system ahead of the 2024 season, Ko appeared as the closing pitcher in the ninth inning against LG, his friendly team. His team was well ahead by 5-2.

Ko Woo-seok allowed the first batter Park Hae-min to hit a heavy hit. Later, he struck out rookie Kim Hyun-jong, but gave up a two-run shot to Lee Jae-won, a follow-up hitter. The second pitch, 153km/h fastball thrown at the ball count 1, was crowded into the center, and Lee Jae-won did not miss it.

Having swallowed the disappointment, Ko struck out Son Ho-young and dealt with Koo Bon-hyeok as a straight hit to the third baseman in his continuous pitching, and ended the game without allowing any additional runs. He defended his team's victory by 5-4, and posted a save, but gave up multiple runs, leaving him anxious.

To Ko, the loss in this game is fatal. During the exhibition game in the 2024 Major League, Ko pitched 4.1 innings in five games, showing sluggish performance with an ERA of 12.46. The WHIP (per-inning on-base percentage) reached a whopping 2.31.

Nevertheless, he was included in the 31-man roster of the Seoul Series. He meant that he would not give up on Ko, who is still in the exhibition game period and needs time to adjust to the U.S. baseball. San Diego manager Mike Shildt said on Wednesday that he would throw well if Ko takes the mound in the opening game.

However, Ko gave two runs to his former team LG at the Gocheok Sky Dome, his most familiar stage. Even KBO league batters did not show overwhelming performance. He had nothing to say even if he was not included in the opening roster of 26.

Coach Silt defended Ko Woo-suk in an interview after the game, saying, "The good news is that Ko Woo-suk made a save by holding an out count," but avoided giving a definite answer on whether Ko Woo-suk will enter the opening game roster, saying, "The roster of the opening series will be decided later by evaluating the players well." In other words, a moment of crisis is approaching for Ko Woo-suk.

Ko Woo-suk, who signed a two-plus-one-year, maximum $9.4 million Major League contract with San Diego in January. He faced a crisis due to his continued sluggishness from the exhibition game. Attention is focusing on whether Ko will be able to overcome the crisis and make the 26th roster of the opening game of the Major League.
