We are developing WAL-G, a cloud backup tool. We used to have only copies of PostgreSQL, but now we support MongoDB, MySQL, FoundationDB and others.
In this talk, I will talk about the features and differences of these databases in terms of backup in the Cloud.

This document discusses three cases where companies implemented automated acceptance testing. In Case 1, automating tests allowed a product to launch on schedule for the first time. Case 2 involved automating tests from the beginning of a new product, allowing releases after each sprint with close customer collaboration. Case 3 highlighted challenges with a large UX project, including creating their own test library and long feedback cycles with much manual testing. The overall learnings emphasized that automated testing enables agility, speeds learning, should involve the whole product, and requires investment in continuous integration while avoiding creating your own automation tools.

This document discusses continuous performance testing (CPT) and introduces the Jagger CPT solution. It provides an overview of why performance testing is important, outlines the principles and goals of CPT, and describes the key parts of the Jagger CPT platform including load generation, metrics collection, test data management, and environment management. It also provides an example customer success story where Jagger was used for continuous performance testing of a large ecommerce site.
This document provides an overview of the JDI (Java UI test automation framework). It discusses features of JDI including being UI element oriented, providing common UI elements and solutions to common problems. It provides examples of how to write tests using JDI annotations and page object pattern. The document also summarizes benefits of JDI such as reducing test code, improving test clarity, reuse across projects. Finally it outlines new features planned for JDI 2.0 including layout verification, page object generator, integration with Selenium and expanding JDI to other languages like Python.
The document discusses testing of geolocation systems. It provides an overview of geolocation, including definitions and importance. It then outlines the speaker's experience and work testing GIS systems. The rest of the document details approaches to testing geolocation, including simulating calls, checking responses and databases, and verifying accuracy. It also discusses common data formats, projections, tools like PostGIS and QGIS, and potential bugs to watch for like coordinate jumbling. The conclusion emphasizes starting simple, practicing to improve, and for tests to grow with knowledge as geolocation is important for future IT.
