Writing test code is good form and is obviously always recommended. Writing GOOD test is an excellent way to fool-proof the code you (I) have so far, but like everything else, it takes practice!

In an attempt to keep it fresh in my mind, here are a few things I found out recently about writing rspec code...

- `travel_to` is useful... But only allowed once.

Okay. That was a bit dramatic. You can actually use `travel_to` in separate blocks as much as you want.

```
context "first context" do
  travel_to("2024-12-25") do
    expect(presents)
  end
end

context "second context" do
  travel_to("2024-12-31") do
    expect(fireworks)
  end
end
```
However, you're (I am) not allowed to do some magical shenanigans such as this

```
context "first context" do
  travel_to("2024-12-25") do
    expect(presents)
    
    travel_to("2024-12-31") do
      expect(fireworks)
    end
  end
end
```
Not only does it look weird and messy, but also you'll get a big angry error. So yeah.
However in some cases it will be inevitable for the whole file to be enclosed in a `travel_to` for some reason or other. And that's when it's a good idea to use `travel_back`!

```
context "first context" do
  travel_to("2024-12-25") do
    expect(presents)
    
  context "second context" do
    before do
      travel_back
    end
    travel_to("2024-12-31") do
      expect(fireworks)
    end
  end
  end
end
```
Simple? Yes. But does it do a good job? Also yes.

**Update:** I have learned an even better method today. The trick is simply to not make subsequent `travel_to` into blocks!

```
context "first context" do
  travel_to("2024-12-25") do
    expect(presents)

    travel_to("2024-12-31")
    expect(fireworks)
  end
end
```

- It's better to not write DSLs dynamically

This one might come as a surprise for some, because it sure did for me. Consider this example

```
describe 'some spec' do
  (1..7).each do |n|
    let!(:"user_#{n}") { create(:user, name: "user#{n}") } 
  end
  # ...
end
```
I thought I was super clever to use iteration like that, but learned from reviewers that it's not good practice. Although it saves time and works fine, it's not reader-friendly.
Instead, a very similar approach can be used through FactoryBot

```
describe 'some spec' do
  let!(:users) { FactoryBot.create_list(:user, 7) } 
  # ...
end
```
This obviously assumes that the name is set in the FactoryBot file

```
FactoryBot.define do
  factory :user do
    sequence(:name) { |n| "user#{n}" }
    # ...
  end
end
```

As I become more acquainted with rspec and keep writing more code, I might come back and edit this document with more interesting finds ☺︎

Let's keep doing our best!

The True Power of a Tech Lead
Published: 2024-06-27 14:17:16


This week I finished reading the book "O Verdadeiro Poder" ("The True Power"), written by Vicente Falconi, which was recommended to me by my friend [Júlio](https://www.linkedin.com/in/j%C3%BAlio-queiroz-caselani-36a05b128/).

Drawing a parallel with the world of software development and the role of a tech lead in a company, understanding all the processes of an organization and how they influence the lives of stakeholders is a responsibility of any tech lead. Moreover, fostering a results-oriented culture within the team is essential.

How much does it cost to develop a feature? What was the real impact of a bug? How much did it cost to stop the team for 3 hours to discuss an issue that wasn’t particularly relevant or could have been resolved via email?

Every new feature and every resolved bug must be aligned with the organization's financial metrics. Besides the technical knowledge required for the tech lead role, we often forget the fundamental management responsibilities that this professional must master.

An effective tech lead should be able to translate strategic goals into clear objectives for their team, ensuring that everyone is aligned and focused on the same goal.

It is a fact that, many times, we cannot know the monetary value of a team or an operation as a whole, but we can track hours, delivered features, and resolved bugs within a sprint or time interval. This would already be a good starting point to have a better view of the team's performance, crucial data that we often overlook.

Falconi's methodology is a guide to achieving challenging goals through planning and focus. Understanding the organization from different angles, whether functionally (horizontally) or departmentally (vertically), is essential for effective management.

In summary, a tech lead must go beyond their technical expertise, developing people management and strategic planning skills to achieve true success. Clearly understanding all the processes of a company and aligning their deliveries with the main objectives of the organization.

Building a Chrome Extension for Email Discovery: Lessons Learned
Tags: chromextension, productivity, react, webscraping
Published: 2024-06-27 14:15:12


Hello Dev.to community! I'm excited to share my journey of building Fast Mail Finder, a Chrome extension for email discovery. In this post, I'll walk you through some key lessons learned during the development process.

## The Problem

As a developer working on outreach projects, I often found myself spending hours manually searching for email addresses. I knew there had to be a better way.

## The Solution

That's how Fast Mail Finder was born. It's a Chrome extension that automates email discovery from web pages. Here are some key features:

- Extract emails from any webpage
- Download emails in CSV/TXT formats
- Automatic email deduplication
- Enhanced search functionality

## Technical Challenges and Solutions

1. **DOM Manipulation**: Efficiently parsing web pages for email addresses required careful DOM traversal. We used MutationObserver to handle dynamically loaded content.

2. **Performance Optimization**: To ensure the extension doesn't slow down browsing, we implemented throttling and debouncing techniques.

3. **Data Privacy**: We prioritized user privacy by storing all data locally in the browser.

4. **Cross-Browser Compatibility**: While initially built for Chrome, we structured our code to be easily portable to other browsers.

## Key Takeaways

1. **User Privacy is Paramount**: Always prioritize user data protection in your projects.
2. **Performance Matters**: Users quickly uninstall slow extensions. Optimize relentlessly.
3. **Solve Real Problems**: Build tools that address genuine user needs.
4. **Continuous Improvement**: User feedback is gold. Use it to iterate and improve your product.

## Open Source Contributions

While Fast Mail Finder isn't open-source, we've learned a lot from the community. We're planning to release some utility functions we developed as open-source soon.

## What's Next?

We're constantly working on improving Fast Mail Finder. Some features in our pipeline:
- AI-powered email guessing
- Integration with popular CRM systems
- Bulk domain email discovery

## Conclusion

Building a Chrome extension has been an exciting journey. I hope sharing these insights helps fellow developers in their projects.

🚀 O Verdadeiro Poder de um Techlead
Published: 2024-06-27 14:12:48


Esta semana terminei a leitura do livro "O Verdadeiro Poder", escrito por Vicente Falconi, uma recomendação de leitura do meu amigo [Júlio](https://www.linkedin.com/in/j%C3%BAlio-queiroz-caselani-36a05b128/).

Traçando um paralelo com o mundo do desenvolvimento de software e o papel do techlead em uma empresa, conhecer todos os processos de uma organização e como eles influenciam a vida dos stakeholders é obrigação de qualquer techlead. Além disso, fomentar uma cultura de resultados em sua equipe é fundamental.

Quanto custa o desenvolvimento de uma feature? Qual foi o impacto real de um bug? Quanto custou parar o time por 3 horas para discutir um assunto sem grande relevância ou que poderia ter sido resolvido por e-mail?

Toda nova feature e todo bug resolvido devem estar alinhados com as métricas financeiras da organização. Além do conhecimento técnico necessário ao cargo de techlead, muitas vezes esquecemos o papel fundamental de gestão que esse profissional deve executar com maestria.

Um Techelead eficaz deve ser capaz de traduzir metas estratégicas em objetivos claros para sua equipe, garantindo que todos estejam alinhados e focados no mesmo objetivo.

É fato que, muitas vezes, não temos como saber o valor monetário de um time ou de uma operação como um todo, mas conseguimos ter um controle de horas, features entregues e bugs resolvidos em uma sprint ou intervalo de tempo. Isso já seria um bom ponto de partida para ter uma melhor visão do desempenho da equipe, dados importantíssimos que muitas vezes deixamos de lado.

A metodologia de Falconi é um guia para atingir metas desafiadoras através do planejamento e foco. Conhecer a organização por diferentes ângulos, seja funcionalmente (horizontal) ou departamentalmente (vertical), é essencial para uma gestão eficaz.

Em suma, um Techlead deve ir além de sua expertise técnica, desenvolvendo habilidades de gestão de pessoas e planejamento estratégico para alcançar o verdadeiro sucesso. Entender com clareza todos os processos de uma empresa e alinhar suas entregas com os objetivos principais da organização.

Acoplamento, Coesão e Encapsulamento
Published: 2024-06-27 14:03:07

São 3 termos muitos recorrentes no desenvolvimento é muito importante conhecê-los.

**Acoplamento** -> é o grau de iterdependência entre dois componentes. Ex: essa bean para funcionar ela precisa dessa outra bean?
 - _Baixo acoplamento_: componente consegue operar praticamente idependente.
 - _Alto acoplamento_: componente tem forte conexão com outro, tornando-o altamente dependente.

**Coesão** -> é o propósito de um componente, impactando na clareza da responsabilidade do componente. Ex: esse bloco de código nessa classe faz sentido estar nela?
 - _Baixa coesão_: o propósito está confuso.
 - _Alta coesão_: o propósito está bem definido.

**Encapsulamento** -> é a capacidade de esconder/isolar um comportamento em um componente. Ex: definição de atributos como **_private_** e utilização de _getter's_ e _setter's_.
