Guia sobre a pirâmide de testes e os níveis de teste de software

·2 views

O texto apresenta a pirâmide de testes como forma comum de organizar os níveis, com mais testes na base e menos no topo. Os níveis de base, como unidade e integração, tendem a ser automatizados via API ou código, enquanto os de topo, como sistema e aceite, usam interface gráfica e são mais lentos e frágeis. A ideia central é antecipar a garantia de qualidade, o chamado shift-left, com ambientes que se aproximam mais da produção conforme se sobe na pirâmide. Cada nível responde a uma pergunta específica, da funcionalidade isolada de uma unidade até a adequação do sistema ao problema de negócio. Por fim, a integração costuma se dividir em pelo menos dois níveis, o de componentes e o de sistema.

MCP Emerges as a Common Standard for Connecting AI Agents to Tools

Model Context Protocol (MCP) is gaining traction as a shared standard for how AI agents connect to external tools and data. Developers currently build separate, one-off integrations for each tool, which makes systems fragile and hard to maintain. MCP proposes a common wire format, a discovery mechanism that lets agents list available tools, and a unified permission model. The article recommends starting with narrow, read-only MCP servers for specific domains, adding human approval for write actions, and versioning servers like any other API. Adopting such a standard could make it easier to swap tools or agent frameworks without rebuilding integrations.

SQL Sublanguages Explained: DDL, DML, DQL, DCL and TCL With a Supermarket Example

This DEV Community article explains the five SQL sublanguages, which group commands by the kind of database operation they perform. It uses a fictional supermarket, Sunrise Supermarket, as a running example for covering each group. The author describes DDL for defining and modifying database structures and touches on related operations such as recording sales and controlling access. The piece walks through practical commands including CREATE TABLE, ALTER TABLE, DROP TABLE, TRUNCATE TABLE and CREATE INDEX.

Fewer crates.io projects go silent on outside pull requests than npm or PyPI

A Porchlamp analysis of open-source projects found that 20.0% of decided crates.io projects are "black holes", meaning they leave most outside pull requests without a human reply, review, or merge for two weeks. By comparison, the figure is 30.0% for npm and 33.8% for PyPI, based on a snapshot taken on 14 October. The Rust subset covers 1,065 crates.io projects, and across all six ecosystems studied, 26.4% of decided projects are black holes. The author cautions that the results are a single snapshot without controls for project size, which correlates with black-hole rates, and that undecided projects are excluded from the percentages.

BIPM to abolish leap seconds from 2025, prompting infrastructure timing changes

The International Bureau of Weights and Measures has decided to stop inserting leap seconds starting in 2025, turning UTC into a linear time scale aligned with TAI. The decision has triggered a surge in online searches and debate among system administrators, IoT developers and high-frequency traders. Systems that still assume the clock may skip or repeat a second risk failures in data pipelines, trade ordering and telecom sessions. The article outlines required adjustments for NTP, PTP, databases, Java applications, scripts and IoT firmware, along with compliance policy updates. It also notes that past leap-second insertions caused outages in 2012 and 2015, underscoring the importance of the transition.
