Design and Achievement of User Interface Automation Testing of Linux Based on Element Tree of DogTail

As Linux gets more popular around the world, the advantage of the open source on software makes people do automated UI test by unified testing framework. UI software testing can guarantee the rationality of User Interface of Linux and accuracy of the UI’s widgets. In order to set free from fuzzy and repeated manual testing, and improve efficiency, this paper achieves automation testing of UI under Linux, and proposes a method to identify and test UI widgets under Linux, which is according to element tree of DogTail automaton testing framework. It achieves automation test of UI under Linux. According to this method, Aiming at the product of Red Hat Subscription Manager under Red Hat Enterprise Linux, it designs the automation test plan of this series of product’s dialogs. After many tests, it is indicated that this plan can identify UI widgets accurately and rationally, describe the structure of software clearly, avoid software errors and improve efficiency of the software. Simultaneously, it also can be used in the internationalization testing for checking translation during software internationalization

catena-Poly[[tetra­aqua­manganese(II)]-μ-5-carboxyl­ato-1-carboxyl­atomethyl-2-oxidopyridinium-κ2 O 5:O 1]

In the title coordination polymer, [Mn(C8H5NO5)(H2O)4]n, the MnII atom is coordinated by two carboxyl­ate O atoms from two 5-carboxyl­ato-1-carboxyl­atomethyl-2-oxidopyridinium (L 2−) ligands and by four water mol­ecules in a distorted octa­hedral geometry. The L 2− ligands bridge the Mn atoms into an infinite chain motif along [100]; the chains are further inter­linked by O—H⋯O hydrogen bonds into a three-dimensional supra­molecular net

Effects of losses in the hybrid atom-light interferometer

Enhanced Raman scattering can be obtained by injecting a seeded light field which is correlated with the initially prepared collective atomic excitation. This Raman amplification process can be used to realize atom-light hybrid interferometer. We numerically calculate the phase sensitivities and the signal-to-noise ratios of this interferometer with the method of homodyne detection and intensity detection, and give their differences between this two methods. In the presence of loss of light field and atomic decoherence the measure precision will be reduced which can be explained by the break of the intermode decorrelation conditions of output modesComment: 9 pages, 7 figure
